i965/fs: Fix segfault in instruction scheduling with LINTERP using last GRF.

The scheduler didn't know about uniform-type accesses, and if a uniform
access was last in a 16-wide, we'd walk off the end of the array.  This
never happened, because we'd never coalesce out all the GRFs, due to a bug
to be fixed in the next commit.
