* iseq.c (iseq_add_local_tracepoint_i): extract aggregate initialization.
See https://travis-ci.org/ruby/ruby/jobs/459881277
* iseq.c (iseq_remove_local_tracepoint_i): ditto.

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
TracePoint. [Feature #15289]
Tragetting TracePoint is only enabled on specified method, proc
and so on, example: `tp.enable(target: code)`.
`code` should be consisted of InstructionSeuqnece (iseq)
(RubyVM::InstructionSeuqnece.of(code) should not return nil)
If code is a tree of iseq, TracePoint is enabled on all of
iseqs in a tree.
Enabled tragetting TracePoints can not enabled again with
and without target.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
to store local hooks.
`rb_iseq_t::aux::trace_events` is renamed to
`global_trace_events` to contrast with `local_hooks`.
* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
to represent how many Threads/Fibers are used this list.
If this field is 0, nobody using this hooks and we can
delete it.
This is why we can remove code from cont.c.
* vm_core.h (rb_vm_t): because of above change, we can eliminate
`rb_vm_t::trace_running` field.
Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.
* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
from `ruby_vm_event_enabled_flags.
* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
enabled targetting TracePoints.
* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
hook list.
* vm_core.h (rb_vm_global_hooks): added for convinience.
* method.h (rb_method_bmethod_t): added to maintain Proc
and `rb_hook_list_t` for bmethod (defined by define_method).
* prelude.rb (TracePoint#enable): extracet a keyword parameter
(because it is easy than writing in C).
It calls `TracePoint#__enable` internal method written in C.
* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.
* vm.c (invoke_bmethod): check def->body.bmethod.hooks.
* vm.c (hook_before_rewind): check iseq->local_hooks
and def->body.bmethod.hooks before rewind by exception.

This patch introduces "oneshot_lines" mode for `Coverage.start`, which
checks "whether each line was executed at least once or not", instead of
"how many times each line was executed". A hook for each line is fired
at most once, and after it is fired, the hook flag was removed; it runs
with zero overhead.
See [Feature #15022] in detail.

This enhances rb_vm_insn_addr2insn which retrieves a decoded insn number
from encoded insn.
The insn data table include not only decoded insn number, but also its
len, trace and non-trace version of encoded insn.
This table can be used to simplify trace instrumentation.

* iseq.c (iseq_init_trace): at ISeq loading time, we need to check
`ruby_vm_event_enabled_flags` to turn on trace instructions.
Seprate this checking code from `finish_iseq_build()` and make
new function. `iseq_ibf_load()` calls this funcation after loading.
* test/ruby/test_iseq.rb: add a test for this fix.

The code fragments that initializes coverage data were scattered into
both parse.y and compile.c. parse.y allocated a coverage data, and
compile.c initialize the data.
To remove this cross-cutting concern, this change moves the allocation
from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c.
For the sake, parse.y just counts the line number of the original source
code, and the number is passed via rb_ast_body_t.

When coverage measurement is enabled, the compiler makes each iseq have
a reference to the counter array of coverage.
Even after coverage measurement is disabled, the reference is kept.
And, if coverage measurement is restarted, a coverage hook will increase
the counter. This is completely meaningless; it brings just overhead.
To remove this meaninglessness, this change removes all the reference
when coverage measuement is stopped.

This is just a refactoring.
The receiver of "invokesuper" was a boolean to represent if it is ZSUPER
or not. This was used in vm_search_super_method to prohibit ZSUPER call
in define_method. (It is currently prohibited because of the limitation
of the implementation.)
This change removes the hack by introducing an explicit flag,
VM_CALL_SUPER, to signal the information. Now, the implementation of
"invokesuper" is consistent with "send" instruction.

when TracePoint is enabled. We're cancelling JIT-ed code execution AFTER
each instruction, but there is no guard before the first insn of method.
To prevent spoiling performance, I don't want to modify the JIT-ed code
to fix this. So this commit replaces `mjit_enabled` check with `mjit_call_p`
check.

The current VM_INSTRUCTION_SIZE is 198, so the linear search
painful during a major GC phase.
I noticed rb_vm_insn_addr2insn2 showing up at the top of some
profiles while working on some malloc-related stuff, so I
decided to attack it.
Most notably, the benchmark/bm_vm3_gc.rb improves by over 40%:

`TRACE_INSN_P` doesn't need to know about encoded iseqs, it just needs
to look at decoded iseqs. We have the decoded iseqs available, so no
reason to look at encoded ones. This change allows us to clear
`original_iseq` from the iseq struct without any segvs (previously,
clearing `original_iseq` would cause the tests to crash).

Directly marking iseq operands allows us to eliminate the "mark array"
stored on ISEQ objects, which will reduce the amount of memory ISEQ
objects consume. This patch changes the iseq mark function to:
* Directly marks ISEQ operands
* Iterate over and mark child ISEQs
It also introduces two flags on the ISEQ object. In order to mark
instruction operands, we have to disassemble the instructions and find
the instruction parameters and types. Instructions may also be
translated to jump addresses. Instruction sequences may get marked by
the GC *while* they're mid flight (being compiled). The
`ISEQ_TRANSLATED` flag is used to indicate whether or not the
instructions have been translated to jump addresses so that when we
decode the instructions we know whether or not we need to go from jump
location back to original instruction or not.
Not all ISEQ objects have any markable objects embedded in their
instructions. We can detect whether or not an ISEQ has markable objects
in the instructions at compile time. If the instructions contain
markable objects, we set a flag `ISEQ_MARKABLE_ISEQ` on the ISEQ object.
This means that during the mark phase, we can skip decompilation if the
flag is *not* set. In other words, we can avoid decompilation of we
know in advance there is nothing to mark.
`once` instructions have an operand that contains the result of a
one-time compilation of a regex. Before this patch, that operand was
called an "inline cache", even though the struct was actually an "inline
storage". This patch changes the operand to be an "inline storage" so
that we can differentiate between caches that need marking (the inline
storage) and caches that don't need marking (inline cache).

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.
