i965/vec4: Only zero out unused message components when there are any.
Otherwise, coordinates with four components would result in a MOV
with a destination writemask that has no channels enabled:
mov(8) g115<1>.F 0D { align16 WE_normal NoDDChk 1Q };
At best, this is stupid: we emit code that shouldn't do anything.
Worse, it apparently causes GPU hangs (observable with Chris's
textureGather test on CubeArrays.)
