ZJIT: Restore test_recompile_no_profile_send test

Keep the original SideExit recompile test alongside the new
final-version test since they cover different behaviors. Remove the
intermediate HIR snapshot since hir_string() now sees the auto-compiled
version as final.

ZJIT: Look up final version status dynamically

Instead of storing is_final_version as a field on Function, compute
it dynamically in convert_no_profile_sends by checking the payload's
version count against MAX_ISEQ_VERSIONS.

ZJIT: Skip convert_no_profile_sends on the final ISEQ version

When an ISEQ has already reached MAX_ISEQ_VERSIONS, converting
no-profile sends to SideExits is counterproductive: the exit fires
every time but can never trigger recompilation. Keep them as Send...

Bump irb version to fix a flaky test

ZJIT: Check native stack before compiling ISEQs (#16576)

• ZJIT: Check native stack before compiling ISEQ

When the native/machine stack is nearly exhausted, don't compile and
enter ZJIT code. JIT-compiled code uses more native stack per call
frame than the interpreter, so falling back to the interpreter avoids...

ZJIT: Fix profile_stack to skip block arg for ARGS_BLOCKARG sends (#16581)

For sends with ARGS_BLOCKARG (e.g. foo(&block)), the block arg sits
on the stack above the receiver and regular arguments. The profiling
(both interpreter and exit profiling) only records types for the...

Remove class alloc check

This checks that the value returned from the function registered with
rb_define_alloc_func is of the correct class. When this was first
introduced in 1fe40b7cc5 (by Matz on 2001-10-03), allocation was done
via user-defined Object#allocate, so it made sense to have a runtime...

[ruby/prism] Also handle string conversion in Ripper.lex

In ripper, both go through the same converion logic.
Needed for rspec, no other failures in their own tests

[ruby/prism] Implement various string start/end events for ripper

tstring_beg in particular is needed by yard.

Before:

1980 examples, 606 failures, 15 pending
After:
1980 examples, 582 failures, 15 pending

Thought it would be more, but oh well. It needs on_sp which I guess is why there are not many new passes...

[ruby/openssl] Fix potential UAF in ossl_crypto_fixed_length_secure_compare

StringValue() can invoke an object's #to_str method, which may execute
arbitrary Ruby code. If #to_str mutates the other string argument during
comparison, its buffer may be reallocated, leaving a previously obtained...
