cpython-lru_cache-weakref: Objects/bytesobject.c annotate

annotate Objects/bytesobject.c @ 43150:1bb63a32a6c8

Per Georg's suggestion, get rid of str.decode() (which always raises an exception) and change bytes.find() to use _getbuffer(), so b"".find("") will raise TypeError instead of SystemError.
