`struct rb_scan_args_t::vargs` is never used 2020-02-03 08:44:51 +09:00
Nobuyoshi Nakada fae537259d
Removed no longer used variable `last_hash`
1. By substituting `n_var` with its initializer, `0 < n_var` is
   equivalent to `argc > argi + n_trail`.
2. As `argi` is non-negative, so `argi + n_trail >= n_trail`, and
   the above expression is equivalent to `argc > n_trail`.
3. Therefore, `f_last` is always false, and `last_hash` is no
   longer used.

Jeremy Evans beae6cbf0f Fully separate positional arguments and keyword arguments
This removes the warnings added in 2.7, and changes the behavior
so that a final positional hash is not treated as keywords or
vice-versa.

To handle the arg_setup_block splat case correctly with keyword
arguments, we need to check if we are taking a keyword hash.
That case didn't have a test, but it affects real-world code,
so add a test for it.

This removes rb_empty_keyword_given_p() and related code, as
that is not needed in Ruby 3.  The empty keyword case is the
same as the no keyword case in Ruby 3.

This changes rb_scan_args to implement keyword argument
separation for C functions when the : character is used.
For backwards compatibility, it returns a duped hash.
This is a bad idea for performance, but not duping the hash
breaks at least Enumerator::ArithmeticSequence#inspect.

Instead of having RB_PASS_CALLED_KEYWORDS be a number,
simplify the code by just making it be rb_keyword_given_p().

卜部昌平 5e22f873ed decouple internal.h headers
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead.  This would significantly
speed up incremental builds.

We take the following inclusion order in this changeset:

1.  "ruby/config.h", where _GNU_SOURCE is defined (must be the very
    first thing among everything).
2.  RUBY_EXTCONF_H if any.
3.  Standard C headers, sorted alphabetically.
4.  Other system headers, maybe guarded by #ifdef
5.  Everything else, sorted alphabetically.

Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

Jeremy Evans 55b7ba3686 Make super in instance_eval in method in module raise TypeError
This makes behavior the same as super in instance_eval in method
in class.  The reason this wasn't implemented before is that
there is a check to determine if the self in the current context
is of the expected class, and a module itself can be included
in multiple classes, so it doesn't have an expected class.

Implementing this requires giving iclasses knowledge of which
class created them, so that super call in the module method
knows the expected class for super calls.  This reference
is called includer, and should only be set for iclasses.

Note that the approach Ruby uses in this check is not robust. If
you instance_eval another object of the same class and call super,
instead of an TypeError, you get super called with the
instance_eval receiver instead of the method receiver.  Truly
fixing super would require keeping a reference to the super object
(method receiver) in each frame where scope has changed, and using
that instead of current self when calling super.

Jeremy Evans a0579f3606 Make prepending a refined module after inclusion not break refinements
After the previous commit, this was still broken. The reason it
was broken is that a refined module that hasn't been prepended to
yet keeps the refined methods in the module's method table. When
prepending, the module's method table is moved to the origin
iclass, and then the refined methods are moved from the method
table to a new method table in the module itself.

Unfortunately, that means that if a class has included the module,
prepending breaks the refinements, because when the methods are
moved from the origin iclass method table to the module method
table, they are removed from the method table from the iclass
created when the module was included earlier.

Fix this by always creating an origin class when including a
module that has any refinements, even if the refinements are
not currently used.  I wasn't sure the best way to do that.
The approach I choose was to use an object flag. The flag is
set on the module when Module#refine is called, and if the
flag is present when the module is included in another module
or class, an origin iclass is created for the module.

Jeremy Evans 5069c5f521 Honor refinements for modules that prepend other modules
This previously did not work, and the reason it did not work is
that:

1) Refining a module or class that prepends other modules places
   the refinements in the class itself and not the origin iclass.

2) Inclusion of a module that prepends other modules skips the
   module itself, including only iclasses for the prepended modules
   and the origin iclass.

Those two behaviors combined meant that the method table for the
refined methods for the included module never ends up in the
method lookup chain for the class including the module.

Fix this by not skipping the module itself when the module is
included.  This requires some code rearranging in
rb_include_class_new to make sure the correct method tables and
origin settings are used for the created iclass.

As origin iclasses shouldn't be exposed to Ruby, this also
requires skipping modules that have origin iclasses in
Module#ancestors (classes that have origin iclasses were already
skipped).

卜部昌平 eb92159d72 Revert https://github.com/ruby/ruby/pull/2486
This reverts commits: 10d6a3aca7 8ba48c1b85 fba8627dc1 dd883de5ba
6c6a25feca 167e6b48f1 7cb96d41a5 3207979278 595b3c4fdd 1521f7cf89
c11c5e69ac cf33608203 3632a812c0 f56506be0d 86427a3219 .

The reason for the revert is that we observe ABA problem around
inline method cache.  When a cache misshits, we search for a
method entry.  And if the entry is identical to what was cached
before, we reuse the cache.  But the commits we are reverting here
introduced situations where a method entry is freed, then the
identical memory region is used for another method entry.  An
inline method cache cannot detect that ABA.

Here is a code that reproduce such situation:

```ruby
require 'prime'

class << Integer
  alias org_sqrt sqrt
  def sqrt(n)
    raise
  end

  GC.stress = true
  Prime.each(7*37){} rescue nil # <- Here we populate CC
  class << Object.new; end

  # These adjacent remove-then-alias maneuver
  # frees a method entry, then immediately
  # reuses it for another.
  remove_method :sqrt
  alias sqrt org_sqrt
end

Prime.each(7*37).to_a # <- SEGV
```

Jeremy Evans 80b5a0ff2a
Make rb_scan_args handle keywords more similar to Ruby methods (#2460)
Cfuncs that use rb_scan_args with the : entry suffer similar keyword
argument separation issues that Ruby methods suffer if the cfuncs
accept optional or variable arguments.

This makes the following changes to : handling.

* Treats as **kw, prompting keyword argument separation warnings
  if called with a positional hash.

* Do not look for an option hash if empty keywords are provided.
  For backwards compatibility, treat an empty keyword splat as a empty
  mandatory positional hash argument, but emit a a warning, as this
  behavior will be removed in Ruby 3.  The argument number check
  needs to be moved lower so it can correctly handle an empty
  positional argument being added.

* If the last argument is nil and it is necessary to treat it as an option
  hash in order to make sure all arguments are processed, continue to
  treat the last argument as the option hash. Emit a warning in this case,
  as this behavior will be removed in Ruby 3.

* If splitting the keyword hash into two hashes, issue a warning, as we
  will not be splitting hashes in Ruby 3.

* If the keyword argument is required to fill a mandatory positional
  argument, continue to do so, but emit a warning as this behavior will
  be going away in Ruby 3.

* If keyword arguments are provided and the last argument is not a hash,
  that indicates something wrong. This can happen if a cfunc is calling
  rb_scan_args multiple times, and providing arguments that were not
  passed to it from Ruby.  Callers need to switch to the new
  rb_scan_args_kw function, which allows passing of whether keywords
  were provided.

This commit fixes all warnings caused by the changes above.

It switches some function calls to *_kw versions with appropriate
kw_splat flags. If delegating arguments, RB_PASS_CALLED_KEYWORDS
is used.  If creating new arguments, RB_PASS_KEYWORDS is used if
the last argument is a hash to be treated as keywords.

In open_key_args in io.c, use rb_scan_args_kw.
In this case, the arguments provided come from another C
function, not Ruby.  The last argument may or may not be a hash,
so we can't set keyword argument mode.  However, if it is a
hash, we don't want to warn when treating it as keywords.

In Ruby files, make sure to appropriately use keyword splats
or literal keywords when calling Cfuncs that now issue keyword
argument separation warnings through rb_scan_args.  Also, make
sure not to pass nil in place of an option hash.

Work around Kernel#warn warnings due to problems in the Rubygems
override of the method.  There is an open pull request to fix
these issues in Rubygems, but part of the Rubygems tests for
their override fail on ruby-head due to rb_scan_args not
recognizing empty keyword splats, which this commit fixes.

Implementation wise, adding rb_scan_args_kw is kind of a pain,
because rb_scan_args takes a variable number of arguments.
In order to not duplicate all the code, the function internals need
to be split into two functions taking a va_list, and to avoid passing
in a ton of arguments, a single struct argument is used to handle
the variables previously local to the function.

This function was created as a variant of st_copy with firing write

It should have more explicit name, such as st_copy_with_write_barrier.
But because it is used only for copying iv_tbl, so I rename it to

to rename it to more general name.

卜部昌平 9ef51b0b89 drop-in type check for rb_define_method
The rb_define_method function takes a pointer to ANYARGS-ed functions,
which in fact varies 18 different prototypes.  We still need to
preserve ANYARGS for storages but why not check the consistencies if
possible.

Q&As:

Q: Where did the magic number "18" came from in the description above?

A: Count the case branch of vm_method.c:call_cfunc_invoker_func().
   Note also that the 18 branches has lasted for at least 25 years.
   See also 200e0ee2fd.

Q: What is this __weakref__ thing?

A: That is a kind of function overloading mechanism that GCC provides.
   In this case for instance rb_define_method0 is an alias of
   rb_define_method, with a strong type.

Q: What is this __transparent_union__ thing?

A: That is another kind of function overloading mechanism that GCC
   provides.  In this case the attributed function pointer is either
   VALUE(*)(int,VALUE*,VALUE) or VALUE(*)(int,const VALUE*,VALUE).

   This is better than void* or ANYARGS because we can reject all
   other possibilities than the two.

Q: What does this rb_define_method macro mean?

A: It selects appropriate alias of the rb_define_method function,
   depending on the arity.

Q: Why the prototype change of rb_f_notimplement?

A: Function pointer to rb_f_notimplement is special cased in
   vm_method.c:rb_add_method_cfunc().  That should be handled by the
   __builtin_choose_expr chain inside of rb_define_method macro
   expansion.  In order to do so, comparison like (func ==
   rb_f_notimplement) is inappropriate for __builtin_choose_expr's
   expression (which must be a compile-time integer constant but the
   address of rb_f_notimplement is not fixed until the linker).  So
   instead we are using __builtin_types_compatible_p, and in doing so
   we need to distinguish rb_f_notimplement from others, by type.

Prevent rb_define_(class|module) classes from moving
Before this commit, classes and modules would be registered with the
VM's `defined_module_hash`.  The key was the ID of the class, but that
meant that it was possible for hash collisions to occur.  The compactor
doesn't allow classes in the `defined_module_hash` to move, but if there
is a conflict, then it's possible a class would be removed from the hash
and not get pined.

This commit changes the key / value of the hash just to be the class
itself, thus preventing movement.

ko1 8f675cdd00 support theap for T_HASH. [Feature #14989]
* hash.c, internal.h: support theap for small Hash.
  Introduce RHASH_ARRAY (li_table) besides st_table and small Hash
  (<=8 entries) are managed by an array data structure.
  This array data can be managed by theap.
  If st_table is needed, then converting array data to st_table data.

  For st_table using code, we prepare "stlike" APIs which accepts hash value
  and are very similar to st_ APIs.

  This work is based on the GSoC achievement
  by tacinight <tacingiht@gmail.com> and refined by ko1.

mame ffb09d8e87 eval.c: rename "rb_frozen_class_p" to "rb_class_modify_check"
Just refactoring.  Despite its name, the function does NOT return a
boolean but raises an exception when the class given is frozen.
I don't think the new name "rb_class_modify_check" is the best, but
it follows the precedeint "rb_ary_modify_check", and is definitely
better than "*_p".

k0kubun ed935aa5be mjit_compile.c: merge initial JIT compiler
which has been developed by Takashi Kokubun <takashikkbn@gmail> as
YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>.

This JIT compiler is designed to be a safe migration path to introduce
JIT compiler to MRI. So this commit does not include any bytecode
changes or dynamic instruction modifications, which are done in original
MJIT.

This commit even strips off some aggressive optimizations from
YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still
fairly faster than Ruby 2.5 in some benchmarks (attached below).

Note that this JIT compiler passes `make test`, `make test-all`, `make
test-spec` without JIT, and even with JIT. Not only it's perfectly safe
with JIT disabled because it does not replace VM instructions unlike
MJIT, but also with JIT enabled it stably runs Ruby applications
including Rails applications.

I'm expecting this version as just "initial" JIT compiler. I have many
optimization ideas which are skipped for initial merging, and you may
easily replace this JIT compiler with a faster one by just replacing
mjit_compile.c. `mjit_compile` interface is designed for the purpose.

common.mk: update dependencies for mjit_compile.c.

internal.h: declare `rb_vm_insn_addr2insn` for MJIT.

vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to
compiler. This avoids to include some functions which take a long time
to compile, e.g. vm_exec_core. Some of the purpose is achieved in
transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are
manually resolved for now. Load mjit_helper.h for MJIT header.
mjit_helper.h: New. This is a file used only by JIT-ed code. I'll
refactor `mjit_call_cfunc` later.
vm_eval.c: add some #ifdef switches to skip compiling some functions
like Init_vm_eval.

win32/mkexports.rb: export thread/ec functions, which are used by MJIT.

include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify
that a function is exported only for MJIT.

array.c: export a function used by MJIT.
bignum.c: ditto.
class.c: ditto.
compile.c: ditto.
error.c: ditto.
gc.c: ditto.
hash.c: ditto.
iseq.c: ditto.
numeric.c: ditto.
object.c: ditto.
proc.c: ditto.
re.c: ditto.
st.c: ditto.
string.c: ditto.
thread.c: ditto.
variable.c: ditto.
vm_backtrace.c: ditto.
vm_insnhelper.c: ditto.
vm_method.c: ditto.

I would like to improve maintainability of function exports, but I
believe this way is acceptable as initial merging if we clarify the
new exports are for MJIT (so that we can use them as TODO list to fix)
and add unit tests to detect unresolved symbols.
I'll add unit tests of JIT compilations in succeeding commits.

* Known issues
  * Code generated by gcc is faster than clang. The benchmark may be worse
    in macOS. Following benchmark result is provided by gcc w/ Linux.
  * Performance is decreased when Google Chrome is running
  * JIT can work on MinGW, but it doesn't improve performance at least
    in short running benchmark.
  * Currently it doesn't perform well with Rails. We'll try to fix this
    before release.

NOTE: Rails performance was somehow a little degraded with JIT for now.
We should fix this.
(At least I know opt_aref is performing badly in JIT and I have an idea
 to fix it. Please wait for the fix.)

normal 244916d43b resolve class name earlier and more consistently
This further avoids class name resolution issues which came
about due to relying on hash table ordering before r53376.

Pre-caching the class name when it is never used raises memory
use, but the overall gain from moving away from st still gives
us a small gain.  Reverting r53376 and this patch and testing with

ko1 e4198a73d4 * make rb_iseq_t T_IMEMO object (type is imemo_iseq).
All contents of previous rb_iseq_t is in rb_iseq_t::body.

  RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
  So RubyVM::ISeq.of(something) method returns different wrapper
  objects but they point the same T_IMEMO/iseq object.
  This patch is big, but most of difference is replacement of
  iseq->xxx to iseq->body->xxx.
  (previous) rb_iseq_t::compile_data is also located to
  rb_iseq_t::compile_data.

ko1 5e8a147480 * method.h: introduce rb_callable_method_entry_t to remove
rb_control_frame_t::klass.
  [Bug #11278], [Bug #11279]
  rb_method_entry_t data belong to modules/classes.
  rb_method_entry_t::owner points defined module or class.
    module M
      def foo; end
    end
  In this case, owner is M.
  rb_callable_method_entry_t data belong to only classes.
  For modules, MRI creates corresponding T_ICLASS internally.
  rb_callable_method_entry_t can also belong to T_ICLASS.
  rb_callable_method_entry_t::defined_class points T_CLASS or
  T_ICLASS.
  rb_method_entry_t data for classes (not for modules) are also
  rb_callable_method_entry_t data because it is completely same data.
  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
  For example, there are classes C and D, and incldues M,
    class C; include M; end
    class D; include M; end
  then, two T_ICLASS objects for C's super class and D's super class
  will be created.
  When C.new.foo is called, then M#foo is searcheed and
  rb_callable_method_t data is used by VM to invoke M#foo.
  rb_method_entry_t data is only one for M#foo.
  However, rb_callable_method_entry_t data are two (and can be more).
  It is proportional to the number of including (and prepending)
  classes (the number of T_ICLASS which point to the module).
  Now, created rb_callable_method_entry_t are collected when
  the original module M was modified. We can think it is a cache.
  We need to select what kind of method entry data is needed.
  To operate definition, then you need to use rb_method_entry_t.
  You can access them by the following functions.
  * rb_method_entry(VALUE klass, ID id);
  * rb_method_entry_with_refinements(VALUE klass, ID id);
  * rb_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
  To invoke methods, then you need to use rb_callable_method_entry_t
  which you can get by the following APIs corresponding to the
  above listed functions.
  * rb_callable_method_entry(VALUE klass, ID id);
  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
  returns rb_callable_method_entry_t.
  You can check a super class of current method by
  rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
  rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
  rb_callable_method_entry_t data.
  We need to consider abotu this field again because it is only
  active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
  defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
  rb_callable_method_t has all information.
* vm_core.h: remove several fields.
  * rb_control_frame_t::klass.
  * rb_block_t::klass.

ko1 18bbd05709 * method.h: split rb_method_definition_t::flag to several flags.
`flag' contains several categories of attributes and it makes us
  confusion (at least, I had confused).
  * rb_method_visibility_t (flags::visi)
    * NOEX_UNDEF     -> METHOD_VISI_UNDEF     = 0
    * NOEX_PUBLIC    -> METHOD_VISI_PUBLIC    = 1
    * NOEX_PRIVATE   -> METHOD_VISI_PRIVATE   = 2
    * NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
  * NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
  * NOEX_BASIC       -> basic (flags::basic, 1 bit)
  * NOEX_MODFUNC     -> rb_scope_visibility_t in CREF
  * NOEX_SUPER       -> MISSING_SUPER (enum missing_reason)
  * NOEX_VCALL       -> MISSING_VCALL (enum missing_reason)
  * NOEX_RESPONDS    -> BOUND_RESPONDS (macro)
  Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
  Background:
    I did not know what "NOEX" stands for.
    I asked Matz (who made this name) and his answer was "Nothing".
    "At first, it meant NO EXport (private), but the original
    meaning was gone."
    This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
  method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
  scope visibility.
  It has 3 method visibilities (public/private/protected)
  and `module_function`.

Motivation and new data structure are described in [Bug #11203].
  This patch also solve the following issues.
  * [Bug #11200] Memory leak of method entries
  * [Bug #11046] __callee__ returns incorrect method name in orphan
                 proc
* test/ruby/test_method.rb: add a test for [Bug #11046].
* vm_core.h: remvoe rb_control_frame_t::me. me is located at value
  stack.
* vm_core.h, gc.c, vm_method.c: remove unlinked_method... codes
  because method entries are simple VALUEs.
* method.h:  Now, all method entries has own independent method
  definititons. Strictly speaking, this change is not essential,
  but for future changes.
  * rb_method_entry_t::flag is move to rb_method_definition_t::flag.
  * rb_method_definition_t::alias_count is now
    rb_method_definition_t::alias_count_ptr, a pointer to the counter.
* vm_core.h, vm_insnhelper.c (rb_vm_frame_method_entry) added to
  search the current method entry from value stack.
* vm_insnhelper.c (VM_CHECK_MODE): introduced to enable/disable
  assertions.

* vm_insnhelper.c: modify SVAR usage.
  When calling ISEQ type method, push CREF information onto method
  frame, SVAR located place. Before this fix, SVAR is simply nil.
  After this patch, CREF (or NULL == Qfalse for not iseq methods)
  is stored at the method invocation.
  When SVAR is requierd, then put NODE_IF onto SVAR location,
  and NDOE_IF::nd_reserved points CREF itself.

ko1 8f88ff4e37 * internal.h: remove struct method_table_wrapper.
struct method_table_wrapper was introduced to avoid duplicate marking
  for method tables.
  For example, `module M1; def foo; end; end` make one method table
  (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
  Classes C1 and C2 includes M1, then two T_ICLASS objects are created
  and they points mtbl too. In this case, three objects (one T_MODULE
  and two T_ICLASS objects) points same mtbl. On marking phase, these
  three objects mark same mtbl. To avoid such duplication, struct
  method_table_wrapper was introduced.
  However, created two T_ICLASS objects have same or shorter lifetime
  than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
  not from T_ICLASS objects. This patch tries marking only from M1.
  Note that one `Module#prepend` call creates two T_ICLASS objects.
  One for refering to a prepending Module object, same as
  `Module#include`. We don't nedd to care this T_ICLASS.
  One for moving original mtbl from a prepending class. We need to
  mark such mtbl from this T_ICLASS object. To mark the mtbl,
  we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
  class `klass`.
* class.c: ditto.
* eval.c (rb_using_refinement): ditto.
* gc.c: ditto.
* include/ruby/ruby.h: define m_tbl directly. The definition of
  struct RClass should be moved to (srcdir)/internal.h.
* method.h: remove decl of rb_free_m_tbl_wrapper().
* object.c: use RCLASS_M_TBL() directly.

keyword arguments/parameters and a splat argument.
  [Feature #10440] (Details are described in this ticket)
  Most of complex part is moved to vm_args.c.
  Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
  * introduce rb_call_info_kw_arg_t to represent keyword arguments.
  * add rb_call_info_t::kw_arg.
  * rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
  * rename rb_iseq_t::arg_keywords to arg_keyword_num.
  * rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
    to represent keyword bitmap parameter index.
    This bitmap parameter shows that which keyword parameters are given
    or not given (0 for given).
    It is refered by `checkkeyword' instruction described bellow.
  * rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
    to represent keyword rest parameter index.
  * add rb_iseq_t::arg_keyword_default_values to represent default
    keyword values.
  * rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
    to represent
      (ci->flag & (SPLAT|BLOCKARG)) &&
      ci->blockiseq == NULL &&
      ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
  * rewrite splat argument code.
  * rewrite keyword arguments/parameters code.
  * merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
  not. If Hash object and all keys are Symbol literals, they are
  compiled to keyword arguments.
* insns.def (checkkeyword): add new instruction.
  This instruction check the availability of corresponding keyword.
  For example, a method "def foo k1: 'v1'; end" is cimpiled to the
  following instructions.
    0000 checkkeyword     2, 0  # check k1 is given.
    0003 branchif         9     # if given, jump to address #9
    0005 putstring        "v1"
    0007 setlocal_OP__WC__0 3   # k1 = 'v1'
    0009 trace            8
    0011 putnil
    0012 trace            16
    0014 leave
* insns.def (opt_send_simple): removed and add new instruction
  "opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
