This commit adds the bytes methods to bytearray, matching CPython. The
existing implementations of these methods for str/bytes are reused for
bytearray with minor updates to match CPython return types.
For details on the CPython behaviour see
https://docs.python.org/3/library/stdtypes.html#bytes-and-bytearray-operations
The work to merge locals tables for str/bytes/bytearray/array was done by
@jimmo. Because of this merging of locals the change in code size for this
commit is mostly negative:
