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.

We need to mark default values for kwarg methods. This also fixes
Bootsnap. IBF iseq loading needed to mark iseqs as "having markable
objects".

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).

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`).

* vm_core.h (rb_iseq_t::aux): add `trace_events` which represents
which events are enabled on this iseq. With this information,
we can skip useless trace-on changes for ISeqs.
* vm_trace.c (RUBY_EVENTS_TRACE_BY_ISEQ): moved to iseq.h and rename it
with ISEQ_TRACE_EVENTS.
* iseq.h: introduce ISEQ_USE_COMPILE_DATA iseq (imemo) flag to represent
COMPILE_DATA is available. In other words, iseq->aux.trace_events is not
available when this flag is set.
* ISEQ_COMPILE_DATA() is changed from a macro.

* vm_core.h: rename absolute_path to realpath because it is expected name.
external APIs (#absolute_path methods) are remained.
* vm_core.h: remove rb_iseq_location_struct::path and
rb_iseq_location_struct::absolute_path and introduce pathobj.
if given path equals to given absolute_path (and most of case
it is true), pathobj is simply given path String. If it is not same,
pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.
This size optimization reduce 8 bytes and
sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes
on 64bit CPU.
To support this change, the following functions are introduced:
* pathobj_path() (defined in vm_core.h)
* pathobj_realpath() (ditto)
* rb_iseq_path() (decl. in vm_core.h)
* rb_iseq_realpath() (ditto)
* rb_iseq_pathobj_new() (ditto)
* rb_iseq_pathobj_set() (ditto)
* vm_core.h (rb_binding_t): use pathobj instead of path. If binding
is given at eval methods, realpath (absolute_path) was caller's
realpath. However, they should use binding's realpath.

* load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq):

We can return any ISeq object as a result value.
