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

which has been developed by Takashi Kokubun <takashikkbn@gmail> as
YARV-MJIT. Many of its bugs are fixed by wanabe <[email protected]>.
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.

(At least I know opt_aref is performing badly in JIT and I have an idea
to fix it. Please wait for the fix.)

Change `%08x` to `%016x` because of two reasons:
* `%016x` demonstrates that we can use two or more digits here.
* Currently, many people uses 64-bit environment.
(I'm unsure if object_id is a good example here, though...)

Don't assume long long == 8 bytes.
If you can assume C99, there are macros named UINT64_C and
such for appropriate integer literal suffixes.
If you can't, no way but do a bitwise or.

Use ALLOCV to allocate struct crypt_data for slightly cleaner and less
error-prone code. It is currently possible it leaks when an invalid
argument is passed to String#crypt or rb_str_new_cstr() fails to
allocate memory.
SIZEOF_CRYPT_DATA macro in missing/crypt.h is removed since it is not
used any longer.

This patch will add pre-allocation in string interpolation.
By this, unecessary capacity resizing is avoided.
For small strings, optimized `rb_str_resurrect` operation is
faster, so pre-allocation is done only when concatenated strings
are large. `MIN_PRE_ALLOC_SIZE` was decided by experimenting with
local machine (x86_64-apple-darwin 16.5.0, Apple LLVM version
8.1.0 (clang - 802.0.42)).
String interpolation will be faster around 72% when large string is created.
