Fix a regression I introduced when I expanded the complex pseudos in
the Mips16 port. A few of the psuedos could either take signed
or unsigned arguments and I did not distinguish the case and improperly
rejected some valid cases that the assembler had previously accepted
when they were pure pseudos that expanded as assembly instructions.
