Weak map references can't move because the st_table needs their address
as a key. But, we also need to remove T_NONE from the map so they
aren't reused.

This code was trying to access memory before unpoisoning it.

This commit just adds poisoning around the freelist to help debugging.
Also verify that the freelist only contains T_NONE objects when checking
the heap integrity

verify_internal_consistency_i and gc_verify_heap_page would walk the
heap, reading data from each slot, but would not unpoison the object
before reading. This commit unpoisons the slot before reading so that
we won't get ASAN errors

* internal.h: move ar_table def to hash.c because other files
don't need to know implementation of ar_table.
* hash.c (rb_hash_ar_table_size): added because gc.c needs to know
the size_of(ar_table).

* gc.c (gc_mark_ptr): this check was introduced by accidentaly
(this is why message is "...", crazy simple) for debugging.
However, this check is useful because if there is T_NONE
object here, we can't know which object points to it.
For debugging reason, I remain this checking code and
set reasonable error message.

* internal.h: rename the following names:
* li_table -> ar_table. "li" means linear (from linear search),
but we use the word "array" (from data layout).
* RHASH_ARRAY -> RHASH_AR_TABLE. AR_TABLE is more clear.
* rb_hash_array_* -> rb_hash_ar_table_*.
* RHASH_TABLE_P() -> RHASH_ST_TABLE_P(). more clear.
* RHASH_CLEAR() -> RHASH_ST_CLEAR().
* hash.c: rename "linear_" prefix functions to "ar_" prefix.
* hash.c (linear_init_table): rename to ar_alloc_table.
* debug_counter.h: rename obj_hash_array to obj_hash_ar.

raise an ArgumentError.

The ruby setting was renamed to HEAP_PAGE_ALIGN_LOG, but the
configure.in (now configure.ac) file was not updated, so the
setting had no effect. The configure setting is unnecessary
after OpenBSD 5.2 and MirOS has been discontinued (with the last
release being over 10 years ago), so it is better to just remove
the related configure setting.
Fix [Bug #13438]
From: Jeremy Evans <code@jeremyevans.net>

* 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.

These APIs are much like <valgrind/memcheck.h>. Use them to
fine-grain annotate the usage of our memory.

In these functions we are intentionally reading memory address
not owned by us. These reads should not be diagnosed.

* hash.c, internal.h: support theap for small Hash.
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.
This work is based on the GSoC achievement
by tacinight <tacingiht@gmail.com> and refined by ko1.

* variable.c: now instance variable space has theap supports.
obj_ivar_heap_alloc() tries to acquire memory from theap.
* debug_counter.h: add some counters for theap.

* transient_heap.c, transient_heap.h: implement TransientHeap (theap).
theap is designed for Ruby's object system. theap is like Eden heap
on generational GC terminology. theap allocation is very fast because
it only needs to bump up pointer and deallocation is also fast because
we don't do anything. However we need to evacuate (Copy GC terminology)
if theap memory is long-lived. Evacuation logic is needed for each type.
See [Bug #14858] for details.
* array.c: Now, theap for T_ARRAY is supported.
ary_heap_alloc() tries to allocate memory area from theap. If this trial
sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on.
We don't need to free theap ptr.
* ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that
if ary is allocated at theap, force evacuation to malloc'ed memory.
It makes programs slow, but very compatible with current code because
theap memory can be evacuated (theap memory will be recycled).
If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT()
instead of RARRAY_CONST_PTR(). If you can't understand when evacuation
will occur, use RARRAY_CONST_PTR().

RARRAY_CONST_PTR() can introduce additional overhead in a futre.
Same fixes for other files.
