  Hi Jiangning,

  Mostly looks reasonable. I've just got one question.

     break;
   case OpMulLane:
+  case OpMulLaneQ:
     s += "__a * " + SplatLane(nElts, "__b", "__c") + ";";
----------------
Why are these distinct? As far as I can see they are treated in exactly the same way by TableGen. Or am I missing something not shown by a simple grep; some endsWith('Q') weirdness or something?
