cpython-lru_cache-weakref: Python/pythonrun.c annotate

annotate Python/pythonrun.c @ 45614:0565130d7d9f 2.4

Backport of r60793: Added checks for integer overflows, contributed by Google. Some are only available if asserts are left in the code, in cases where they can't be triggered from Python code.
