target-mips: fix translation of MT instructions
The translation of dmt/emt/dvpe/evpe was doing the moral equivalent of: int x; ... /* no initialization of x */ x = f (x); which confused later bits of TCG rather badly, leading to crashes. Fix the helpers to only return results (those instructions have no inputs), and fix the translation code accordingly.
