vc4: Allow multi-instruction QIR nodes to get VPM optimization.

There used to be multi-instruction operations that would use src[] twice,
which is why we couldn't do some optimizations on them.  This is no longer
the case.

total instructions in shared programs: 77973 -> 77969 (-0.01%)
instructions in affected programs:     84 -> 80 (-4.76%)
total estimated cycles in shared programs: 234165 -> 234157 (-0.00%)
estimated cycles in affected programs:     92 -> 84 (-8.70%)
