gh-91421: Use constant value check during runtime (GH-91422) 
The left-hand side expression of the if-check can be converted to a
constant by the compiler, but the addition on the right-hand side is
performed during runtime.

Move the addition from the right-hand side to the left-hand side by
turning it into a subtraction there. Since the values are known to
be large enough to not turn negative, this is a safe operation.

Prevents a very unlikely integer overflow on 32 bit systems.

Fixes GH-91421.

bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049) 
Add "z" format specifier to coerce negative 0 to zero.

See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion.
This covers `str.format()` and f-strings.  Old-style string interpolation is not supported.

bpo-47164: Add _PyASCIIObject_CAST() macro (GH-32191) 
Add macros to cast objects to PyASCIIObject*, PyCompactUnicodeObject*
and PyUnicodeObject*: _PyASCIIObject_CAST(),
_PyCompactUnicodeObject_CAST() and _PyUnicodeObject_CAST(). Using
these new macros make the code more readable and check their argument
with: assert(PyUnicode_Check(op)).

Remove redundant assert(PyUnicode_Check(op)) in macros using directly
or indirectly these new CAST macros.

Replacing existing casts with these macros.

 (Contributed by Fabio Zadrozny)

* Make accesses to a frame's `f_locals` safe from C code, not relying on calls to `PyFrame_FastToLocals` or `PyFrame_LocalsToFast`.

* Document new `PyFrame_GetLocals` C-API function.

bpo-46841: Quicken code in-place (GH-31888) 
* Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place.

* Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches

* _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms.

* _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches

* _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup

* _Py_Quicken is renamed to _PyCode_Quicken

* _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview).

* Do not emit unused nonzero opargs anymore in the compiler.
