tcg: Pass the opcode width to target_parse_constraint
This will let us choose how to interpret a given constraint depending on whether the opcode is 32- or 64-bit. Which will let us share more constraint combinations between opcodes. At the same time, change the interface to return the advanced pointer instead of passing it in/out by reference.
