Matt Pharr 290032f4f5 Be more careful about using the right mask when emitting gathers. ...

Specifically, we had been using the full mask for all gathers, rather than
using the internal mask when we were loading from locally-declared arrays.
Thus, given code like:

  uniform float x[programCount] = { .. . };
  float xx = x[programIndex];

Previously we weren't generating a plain vector load to initialize xx, when
this code was in a function where it wasn't known that the mask was all on,
even though it should have.  Now it does.
