gh-143050: Add helper _PyLong_InitTag() (#147956) 
With this we can assume, that _PyLong_SetSignAndDigitCount() and
_PyLong_SetDigitCount() operate on non-immortal integers.

GH-126910: Make _Py_get_machine_stack_pointer return the stack pointer (#147945) 
* Make _Py_get_machine_stack_pointer return the stack pointer (or close to it), not the frame pointer

* Make ``_Py_ReachedRecursionLimit`` inline again
* Remove ``_Py_MakeRecCheck`` relacing its use with ``_Py_ReachedRecursionLimit``
* Move stack swtiching check into ``_Py_CheckRecursiveCall``

gh-147944: Increase range of bytes_per_sep (GH-147946) 
Accepted range for the bytes_per_sep argument of bytes.hex(),
bytearray.hex(), memoryview.hex(), and binascii.b2a_hex()
is now increased, so passing sys.maxsize and -sys.maxsize is now
valid.

gh-143050: Correct PyLong_FromString() to use _PyLong_Negate() (#145901) 
The long_from_string_base() might return a small integer, when the
_pylong.py is used to do conversion.  Hence, we must be careful here to
not smash it "small int" bit by using the _PyLong_FlipSign().

gh-145779: Improve classmethod/staticmethod scaling in free-threaded build (#145826) 
Add special cases for classmethod and staticmethod descriptors in
_PyObject_GetMethodStackRef() to avoid calling tp_descr_get, which
avoids reference count contention on the bound method and underlying
callable. This improves scaling when calling classmethods and
staticmethods from multiple threads.

Also refactor method_vectorcall in classobject.c into a new _PyObject_VectorcallPrepend() helper so that it can be used by
PyObject_VectorcallMethod as well.

gh-145037: Fix Emscripten trampoline with emcc >= 4.0.19 (#145038) 
This undoes a change made as a part of PR 137470, for compatibility with EMSDK
4.0.19. It adds `emscripten_trampoline` field in `pycore_runtime_structs.h`
and initializes it from JS initialization code with the wasm-gc based trampoline
if possible. Otherwise we fall back to the JS trampoline.
