Remove redundant _PyFrame_GetCode

[WolframAlph]

No need to call _PyFrame_GetCode(cframe), it is already passed as co:

cpython/Objects/typeobject.c

Line 10546 in d91e43e

int res = super_init_without_args(frame, _PyFrame_GetCode(frame), &type, &obj);

Hi! Thanks for the pull request. As a general rule, CPython doesn't accept "code cleanup" pull requests that don't fix an actual bug or add a feature; it's not worth the code churn and risk of breakage. I do think this change is correct and safe, and there could in principle be a performance impact, though I doubt its detectable (especially since in Python 3.12 with the LOAD_SUPER_ATTR opcode, this function is rarely used anymore.)

Also, per the dev guide, all CPython PRs (unless they are fixing e.g. just a doc typo) should be linked to a separate issue describing the problem.

Thanks for review! For unoptimised build it produces less assembly while behaviour is the same, but it's true that for optimised build, generated assembly is the same. Came across this while investigating #113212, so decided maybe it makes sense to modify it, but I get your point. Closing this PR.
