Similar to rb_typeddata_is_kind_of, except for that inherited type
is not an instance.

* iseq.c (iseqw_s_of): return given object if the given object is
a `RubyVM::InstructionSequence`. We can specify ISeq for
`TracePoint#enable(target:)`.

* vm_trace.c: `TracePoint#enable(target_line:)` is supported.
This option enables a hook only at specified target_line.
target_line should be combination with target and :line event.

* 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.

The former states explicitly that the argument must be a literal,
and can optimize away `strlen` on all compilers.

I assume we always prefix rb_ to non-static functions to avoid conflict.
These functions are not exported and safe to be renamed.
iseq.h: ditto
compile.c: ditto

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%:

* iseq.c (get_insn_info_succinct_bitvector): If
VM_CHECK_MODE is 0, `body->insns_info.positions` is

This commit adds write barriers for objects marked from `rb_iseq_mark`.
r62851 introduced direct marking from iseqs to:
* keyword arg default values
* catch table iseqs
* VALUEs embedded in encoded instructions
This patch adds missing write barrier calls to those references.

Bootsnap. IBF iseq loading needed to mark iseqs as "having markable
