freedreno/ir3: handle "holes" in inputs
If, for example, only the x/y/w components of in.xyzw are actually used,
we still need to have a group of four registers and assign all four
components. The hardware can't write in.xy and in.w to discontiguous
registers. To handle this, pad with a dummy NOP instruction, to keep
the neighbor chain contiguous.
This fixes a problem noticed with firefox OMTC.
