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.

and benchmarks against so_k_nucleotide seem to indicate little
or no performance change compared to before.

Hash#merge, merge!, and update could merge exactly two hashes.
Now, they accepts zero or more hashes as arguments so that it can merge
hashes more than two.

Both methods Hash#length and Hash#size share the same source code in
Ruby, but they also share the same documentation. Now when you look at
the documentation of Hash#size you only see examples for Hash#length,
which is confusing. This commit includes Hash#size in the examples and
also remarks that both methods are equivalent to each other.

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.

* hash.c (prime2): turned into a uint32_t prime, as the lower
32bits, non-prime part only was used always.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61473 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
Current check for __uint128_t in hash.c is not valid, since it ignores
compilers other than gcc. We hit this on lcc on e2k platform.
Configure script properly checks from 128-bit data types support and
sets HAVE_UINT128_T accordingly. This approach is already used within
ruby at bignum.c, random.c, etc.
Probably hash.c is an overlooked remnant of old days. This patch fixes
this.

Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq. So, it just measured
methods defined by `def` keyword.
This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).

Sometimes, size of a hash can be calcluated a priori. By providing
such info to the constructor we can avoid unnecessary internal re-
allocations. This can boost for instance creation of hash literals.
