Daniel Sanders 556791680d [mips][ias] Range check uimm5 operands and fix several bugs this revealed.
Summary:
The bugs were:
* append, prepend, and balign were not tested
* balign takes a uimm2 not a uimm5.
* drotr32 was correctly implemented with a uimm5 but the tests expected
  '52' to be valid.
* li/la were implemented with a uimm5 instead of simm32. simm32 isn't
  completely correct either but I'll fix that when I get to simm32.

A notable omission are some of the shift instructions. Several of these
have been implemented using a single uimm6 instruction (rather than two
uimm5 instructions and a CodeGen-only uimm6 pseudo). These will be updated
in the uimm6 patch.
