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.

gh-129236: Use stackpointer in free threaded GC (#129240) 
The stack pointers in interpreter frames are nearly always valid now, so
use them when visiting each thread's frame. For now, don't collect
objects with deferred references in the rare case that we see a frame
with a NULL stack pointer.

gh-129185: Simplify PyTraceMalloc_Track() (#129256) 
Since tracemalloc uses PyMutex, it becomes safe to use TABLES_LOCK()
even after _PyTraceMalloc_Fini(): remove the "pre-check" in
PyTraceMalloc_Track() and PyTraceMalloc_Untrack().

PyTraceMalloc_Untrack() no longer needs to acquire the GIL.

_PyTraceMalloc_Fini() can be called earlier during Python
finalization.

* Test also PyTraceMalloc_Untrack() without the GIL
* PyTraceMalloc_Untrack() now gets the GIL.
