gh-128130: Fix unhandled keyboard interrupt data race (gh-129975) 
Use an atomic operation when setting
`_PyRuntime.signals.unhandled_keyboard_interrupt`. We now only clear the
variable at the start of `_PyRun_Main`, which is the same function where
we check it.

This avoids race conditions where previously another thread might call
`run_eval_code_obj()` and erroneously clear the unhandled keyboard
interrupt.

gh-130019: Fix data race in _PyType_AllocNoTrack (gh-130058) 
The reference count fields, such as `ob_tid` and `ob_ref_shared`, may be
accessed concurrently in the free threading build by a `_Py_TryXGetRef`
or similar operation. The PyObject header fields will be initialized by
`_PyObject_Init`, so only call `memset()` to zero-initialize the remainder
of the allocation.

gh-130030: Fix crash on 32-bit Linux with free threading (gh-130043) 
The `gc_get_refs` assertion needs to be after we check the alive and
unreachable bits. Otherwise, `ob_tid` may store the actual thread id
instead of the computed `gc_refs`, which may trigger the assertion if
the `ob_tid` looks like a negative value.

Also fix a few type warnings on 32-bit systems.

gh-129201: Use prefetch in GC mark alive phase. (gh-129203) 
For the free-threaded version of the cyclic GC, restructure the "mark alive" phase to use software prefetch instructions.  This gives a speedup in most cases when the number of objects is large enough.  The prefetching is enabled conditionally based on the number of long-lived objects the GC finds.

gh-126835: Move optimization of constant sequence creation from codegen to CFG (#129426) 
Codegen phase has an optimization that transforms
```
LOAD_CONST x
LOAD_CONST y
LOAD_CONXT z
BUILD_LIST/BUILD_SET (3)
```
->
```
BUILD_LIST/BUILD_SET (0)
LOAD_CONST (x, y, z)
LIST_EXTEND/SET_UPDATE 1
```
This optimization has now been moved to CFG phase to make #128802 work.
