This is a resubmittal. For some reason it broke the bots yesterday
but I cannot reproduce the problem and have scrubed my sources and
even tested with llvm-lit -v --vg.
The Mips RDHWR (Read Hardware Register) instruction was not
tested for assembler or dissassembler consumption. This patch
adds that functionality.
