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

annotate Python/sysmodule.c @ 28572:faeb708bacc4 2.2

Backport: PyErr_NormalizeException(): in the type==NULL test, we should simply return. Setting an exception can mess with the exception state, and continuing is definitely wrong (since type is dereferenced later on). Some code that calls this seems to be prepared for a NULL exception type, so let's be safe rather than sorry and simply assume there's nothing to normalize in this case.
