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".

shyouhei b5d6db65b4 `int isnan(double)` is a POSIXism
- `isnan` is something relatively new.  We need to provide one for
  those systems without it.  However:
- X/Open defines `int isnan(double)`. Note the `int`.
- C99 defines `isnan(x)` to be a macro.
- C++11 nukes them all, undefines all the "masking macro"s, and
  defines its own `bool isnan(double)`.  Note the `bool`.
- In C++, `int isnan(double)` and `bool isnan(double)` are
  incompatible.
- So the mess.

k0kubun 288b44328d Export some missing symbols for MJIT
tool/ruby_vm/views/_insn_name_info.erb: on Linux, rb_vm_insn_name_offset
was needed to compile with --jit-debug (Usually --jit-debug requires
more symbols than the situation without --jit-debug because -O2 skips
some functions to compile).

vm.c: when running transform_mjit_header.rb with --jit-wait,
rb_source_location_cstr was repoted to be missing.

string.c: ditto, for rb_str_eql
numeric.c: ditto, for rb_float_eql

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.

 to fix it. Please wait for the fix.)

normal 7e669f40be ruby/ruby.h: remove unnecessary exports from C-API
Needlessly exporting can reduce performance locally and increase
binary size.

Increasing the footprint of our C-API larger is also detrimental
to our development as it encourages tighter coupling with our
internals; making it harder for us to preserve compatibility.

If some parts of the core codebase needs access to globals,
internal.h should be used instead of anything in include/ruby/*.

shyouhei de9d264026 there is no guarantee that mode_t is as wide as int
POSIX only defines mode_t to be "an integer typea", and in fact
MacOS defines it to be uint16_t.  We didn't have NUM2USHORT before
so it did not make sense but now that we have it.  Why not check
apptopriately.

shyouhei 3ca0948f68 INFINITY is float. That of double is HUGE_VAL.
It seems HUGE_VAL is already used. Why not eliminate INTINITY.
NAN is also float. That of double is called nan(). This is also
fixed.

win32ole.c includes ALLOCA_N(struct myCPINFOEX, 1).  On such case
it is not a wise idea to align to the size of that struct.

rb_setup_fake_str() can take arbitrary char* address, typicalluy
C string literals.  These arguments have no guarantee of
alignment at all.  It was not a wise idea for me to think
RSTRING_PTR can be aligned.

Before this NORETURN was checked only for __attribute__ or __declspec,
but nowadays other ways are there to tell compilers that a function
never returns.  Take them into account.

shyouhei df9a70900a __builtin_alloca_with_align for optimal memory access
ALLOCA_N takes type arugment.  It is natural that the returned
value to be used as an array of type, thus type-aligned.
Luckily GCC has a builtin to tell compiler such alignment info.
This should generate beter instructions.

shyouhei f089a52865 __attibute__((__aligned__)) for RSTRING_PTR()
For instance array.c:rb_ary_product() uses RSTRING_PTR() as an
array of int. So to avoid misaligned memory access RSTRING_PTR()
must at least be sizeof(int)-aligned.  However the type of
RSTRING_PTR() is char*, which of course can expect alignment as
much as 1.  This is a problem.

The reality is, there is no misaligned memory access because the
memory region behind RSTRING_PTR() is allocated using malloc().
Memory regions returned from malloc() are always aligned
appropriately.  So let's tell the compiler about this information.
It seems GCC, clang, and MSVC have such feature.
