7f25b8f5fb Disable TSAN for rb_gc_mark_machine_context 
Previously this was listed as a suppression, but we actually want this
permanently unsanitized. This should be faster and more reliable since
TASN won't have to match against symbolicated backtraces.

3ad2019259 Extract vm_locked_by_ractor_p 
This introduces a new method to encapsulate checking whether the current
Ractor owns the vm->ractor.sync lock. This allows us to disable TSan on
it since that operation should be safe, and still get validation of
other uses.

d67d169aea Use atomics for system_working global 
Although it almost certainly works in this case, volatile is best not
used for multi-threaded code. Using atomics instead avoids warnings from
TSan.

This also simplifies some logic, as system_working was previously only
ever assigned to 1, so --system_working <= 0 should always return true
(unless it underflowed).

e1f544c1cf Always look for the top-level RBasic in LLDB scripts 
`rp` and other commands were broken for me because they always showed
the object as a T_NONE.

The reason was that instead of returning the type `struct RBasic`,
FindFirstType("struct RBasic") was returning
`yjit::cruby::autogened::RBasic`.

Explicitly asking for the top-level RBasic by prefixing it with `::` is
enough to fix those commands.

Fix lldb debug scripts (#13048) 
In ruby/ruby#13008 `RVALUE` was removed without replacement. This means
the lldb scripts that relied on `RVALUE` stopped working.

I updated the ones that were using it just for the bytesize to use
`slot_size` and then round to the nearest power of 40. We can't use
`slot_size` directly because in debug mode it's `48` but `RVALUE` is
`40` bytes.

For the `as_type` method, I updated it to check the type. It's only used
for `bignum` and `array` so that's a simple change.

Lastly, for the `dump_page` method I replaced it with `struct free_slot`
since that's looking at the freelist.

`struct RVALUE` has been removed from all the scripts and I verified
that `rp` is fixed. I'm not confident the `dump_page` method is fixed,
the freelist looks off, but for now this gets us closer.

8e7df4b7c6 Rename size_pool -> heap 
Now that we've inlined the eden_heap into the size_pool, we should
rename the size_pool to heap. So that Ruby contains multiple heaps, with
different sized objects.

The term heap as a collection of memory pages is more in memory
management nomenclature, whereas size_pool was a name chosen out of
necessity during the development of the Variable Width Allocation
features of Ruby.

The concept of size pools was introduced in order to facilitate
different sized objects (other than the default 40 bytes). They wrapped
the eden heap and the tomb heap, and some related state, and provided a
reasonably simple way of duplicating all related concerns, to provide
multiple pools that all shared the same structure but held different
objects.

Since then various changes have happend in Ruby's memory layout:

* The concept of tomb heaps has been replaced by a global free pages list,
  with each page having it's slot size reconfigured at the point when it
  is resurrected
* the eden heap has been inlined into the size pool itself, so that now
  the size pool directly controls the free_pages list, the sweeping
  page, the compaction cursor and the other state that was previously
  being managed by the eden heap.

Now that there is no need for a heap wrapper, we should refer to the
collection of pages containing Ruby objects as a heap again rather than
a size pool

89cfc15207 [Feature #20257] Rearchitect Ripper 
Introduce another semantic value stack for Ripper so that
Ripper can manage both Node and Ruby Object separately.
This rearchitectutre of Ripper solves these issues.
Therefore adding test cases for them.

* [Bug 10436] https://bugs.ruby-lang.org/issues/10436
* [Bug 18988] https://bugs.ruby-lang.org/issues/18988
* [Bug 20055] https://bugs.ruby-lang.org/issues/20055

Checked the differences of `Ripper.sexp` for files under `/test/ruby`
are only on test_pattern_matching.rb.
The differences comes from the differences between
`new_hash_pattern_tail` functions between parser and Ripper.
Ripper `new_hash_pattern_tail` didn’t call `assignable` then
`kw_rest_arg` wasn’t marked as local variable.
This is also fixed by this commit.
