Hiroshi SHIBATAandClaude Opus 5.5 9f323525f8 Fix error paths of lldb rbbt 
Without an argument, or with an expression that failed to evaluate, rbbt raised a Python exception instead of reporting the problem. Evaluating without a process referred to an undefined `target` as well.

Hiroshi SHIBATAandClaude Opus 5.5 9dd04cb1f8 Update rp expectations in test_lldb_cruby.rb 
rp has long printed the GC bits of a heap object before its type, and every string as a `const char` array since e078352a78, so three of the four tests were failing.

Hiroshi SHIBATAandClaude Opus 5.5 f0ee6a3a9d Read ZJIT frames in lldb rbbt as CFP_ISEQ does 
ZJIT does not write `_iseq` and `pc` of its frames until they are materialized, so rbbt dropped them or printed stale ones. Read the JIT frame instead when ZJIT is enabled, as CFP_ISEQ() and CFP_PC() do.

Hiroshi SHIBATAandClaude Opus 5.5 a482d0cb69 Read iseq strings in lldb rbbt through the target 
A core saved with `process save-core -s modified-memory` lacks static strings such as `<main>`, which SBProcess cannot read, so rbbt printed `error!!` as the label. SBTarget falls back to the object file.

Hiroshi SHIBATAandClaude Opus 5.5 62f61596f0 Follow the cfp->_iseq rename in lldb rbbt 
226f37059e renamed the field, so `->iseq` no longer resolved and rbbt skipped every ISEQ frame, printing only CFUNC ones.

Hiroshi SHIBATAandClaude Opus 5.5 b4bc7bc702 misc/gdb.py: Fix the swapped Params and Locals conditions 
cfp printed Params only when the frame had locals and Locals only when it had params, so a method with arguments and no locals showed an empty Locals instead of its arguments.

Hiroshi SHIBATAandClaude Opus 5.5 1a5a8c761d misc/gdb.py: Read the frame iseq through cfp_iseq_pc 
The cfp command still read cfp->iseq, which 226f37059e renamed to _iseq, so it stopped with "There is no member named iseq." on every frame. cfp_iseq_pc in .gdbinit also gives the right iseq for ZJIT frames.

Peter Zhu 1d8d84b3d6 Increase IMEMO_MASK by one bit 
We are out of imemo types because IMEMO_MASK uses 4 bits and we have 16
imemo types. This makes it not possible to experiment with new imemo types,
so we can increase it by one bit to have 16 more imemo types.

John Hawthorn 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

John Hawthorn 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).

Étienne Barrié 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.

Eileen 5aa05f179c 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.

Matt Valentine-House 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

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.
