"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".

First we allocate and populate an rb_proc_t struct inline to avoid
unnecessary zeroing of the large struct. Inlining speeds up callers as
this takes many parameters to ensure correctness. We then call the new
rb_proc_wrap function to create the object.
rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but
we only use it inside rb_proc_alloc. We must call this before
the compiler may clobber VALUE parameters passed to rb_proc_alloc.

of IFUNC frame.
When `rb_binding_new_with_cfp()' is called, VM finds out the first
normal (has iseq) frame and create a binding object of this frame
and create Env objects. `ep's of related frames are updated
(`ep's point Env object managed spaces).
However, `ep' of skipped IFUNC frame was not updated and
old invalid `ep' was remained. It causes serious problems.
To solve this issue, permit IFUNC to create binding.
(Maybe there is no problem on it)
[ruby-dev:46908] [ruby-trunk - Bug #7774]
* test/ruby/test_settracefunc.rb: add a test.
* vm.c (rb_vm_get_binding_creatable_next_cfp), vm_core.h: added.
* vm_trace.c: fix to use `rb_vm_get_binding_creatable_next_cfp()'.

This method type is for optimized CFUNC such as Fixnum#+ and so on.
This feature is half-baked and no way to use them.
[Background]
Now, VM has opt_plus instructions to optimize `+' methods for
some Classes (such as Fixnum, Float (flonum)). We call this
type of instructions as `specialized instructions'.
This simple technique improve simple program dramatically.
However, we can make specialized instructions for only several
types (classes) and selectors (method names) because a large
instruction will be slow. In other words, this technique has no
extensibility.
To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
introduced (r37198). This type is a variant of CFUNC, but called
their functiions directly without building a method frame.
Any CFUNC method can be defined as frameless methods if a method
is not needed to make method frame. Frameless methods are faster
as specialized instructions (a bit slower, but no need to care).
No problem described at
http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
because this technique doesn't see class, but see method body
itself. Alias is also no problem.
[Problem]
However, we can't set frameless method type for polymorphic methods
such as Array#[]. Necessity for method frame depends on which
parameter type. For example, Fixnum#+ needs method frame if
coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
flexible and need more tuning to introduce it.
Expected behavior of frameless method type may be:
result = optimized_cfunc(params); /* call optimized cfunc */
if (result == Qundef) { result = normal_cfunc(); }
This is why I say this feature is half-baked.
We need to learn primitive method in Smalltalk more.
(I heard this name at RubyConf Taiwan this month. Thanks!)
[Conclusion]
Nobody may use this feature and there is no compatibility issue.
This feature goes to next minor (2.1?).
* proc.c (rb_method_entry_arity): ditto.
* vm_eval.c, vm_insnhelper.c, vm_method.c: ditto.

* proc.c (umethod_bind): allow another form of method transplanting
from a module via UnboundMethod. [ruby-core:34267][Feature #4254]

rb_method_type_t is not a number and "_MAX" causes misunderstanding.
* proc.c (rb_method_entry_arity): ditto.
* vm_eval.c (vm_call0_body): ditto.
* vm_insnhelper.c (vm_call_method): ditto.

* method.h (rb_method_flag_t): name a magic number for NOEX_SAFE and
NOEX_WITH as NOEX_SAFE_SHIFT_OFFSET.
* method.h (rb_method_type_t, method_optimized_type): C89 forbids a
comma after the last element in enum.
* proc.c (rb_method_entry_arity), vm_eval.c (vm_call0_body),
vm_insnhelper.c (vm_call_method): add VM_METHOD_TYPE__MAX case.
