vc4: Allow merging instructions with SF set where the other writes NOP.
I'm not sure how I managed to write the SF merge code
(7d8b79f398f18ed7bb48a74b1b82950e2f08abad) without allowing merges with
NOPs. *Everything* we try to merge with will have a NOP on one or the
other side of the instruction, and that's why that commit showed no
benefit.
total instructions in shared programs: 99347 -> 95128 (-4.25%)
instructions in affected programs: 91906 -> 87687 (-4.59%)
3DMMES performance +2.57105% +/- 0.135276% (n=6,8)
