Daniel Sanders 878dadf925 [mips] Range check uimm16 and fix several bugs this revealed.
Summary:
The bugs were:
* teq and similar take 4-bit unsigned immediates on microMIPS.
* teqi and similar have side-effects like teq do.
* shll_s.w and shra_r.w take 5-bit unsigned immediates.
* The various DSP ext* instructions take a 5-bit immediate.
* repl.qh takes an 8-bit unsigned immediate.
* repl.ph takes a 10-bit unsigned immediate.
* rddsp/wrdsp take a 10-bit unsigned immediate.
* teqi and similar take signed 16-bit immediates (10-bit for microMIPS).
* Out-of-range immediate macros for or/xor take a simm32/simm64 depending
  on architecture. I'll fix the simm64 case properly when I reach simm32.

lui is a bit more lenient than GAS and accepts signed immediates in addition
to unsigned. This is because MipsMCExpr can produce signed values when
constant folding and it currently lacks a way of knowing it should fold to
an unsigned value.
