Add a LoadUB (unsigned byte) and LoadUI (unsigned int) opcode class so we have these load optimizations in the first place and do not need to handle them in the matcher.
These classes will handle code like, e.g.:
bytearray[i] & 0xFF
intarray[i] & 0xFFFFFFFF
These classes will handle code like, e.g.:
bytearray[i] & 0xFF
intarray[i] & 0xFFFFFFFF
