Nathan Froyd 9ed5726c04 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.
