36cd99ffe9 [mips] Correct the definitions of some control instructions 
Correct the definitions of ei, di, eret, deret, wait, syscall and break.
Also provide microMIPS specific aliases to match the MIPS aliases.

Additionally correct the definition of the wait instruction so that
it is present in the instruction mapping tables.

4cf61e5269 [mips] Range check uimm20 and fixed a bug this revealed. 
Summary:
The bug was that dextu's operand 3 would print 0-31 instead of 32-63 when
printing assembly. This came up when replacing
MipsInstPrinter::printUnsignedImm() with a version that could handle arbitrary
bit widths.

MipsAsmPrinter::printUnsignedImm*() don't seem to be used so they have been
removed.
