mesa: Reduce the source channels considered in optimization passes.

Depending on the writemask or the opcode, we can often trim the source
channels considered used for dead code elimination.  This saves actual
instructions on 965 in the non-GLSL path for glean glsl1, and cleans up
the writemasks of programs even further.
