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

annotate Python/errors.c @ 12970:63436719d12e legacy-trunk

Add new parser error code, E_OVERFLOW. This error is returned when the number of children of a node exceeds the max possible value for the short that is used to count them. The Python runtime converts this parser error into the SyntaxError "expression too long."
