(REGISTER_TYPES): Adjust for h8/300h.

(REGISTER_RAW_SIZE): Ditto
(REGISTER_VIRTUAL_TYPE): Use builtin_type_unsigned_long for regs on the h8/300h
(ints may still be 16 bits).
(EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE, EXTRACT_STRUCT_VALUE_ADDRESS):
Add FIXME's for h8/300h.  Some thought needed here.
