vc4: Add support for coalescing ALU ops into tex_[srtb] MOVs.
This isn't as complete as I would like (can't merge interpolation because
of the implicit r5 dependency, doesn't work with control flow), but this
was cheap and easy.
Improves 3DMMES Taiji performance by 1.15353% +/- 0.299896% (n=29, 16)
total instructions in shared programs: 99810 -> 99059 (-0.75%)
instructions in affected programs: 10705 -> 9954 (-7.02%)

vc4: Restructure VPM write optimization into two passes.
For texturing, there won't be a fixed limit on how many writes there are,
so we need to compute uses up front.

vc4: Split optimizing VPM writes from VPM reads.
The VPM write logic will be basically the same as the texture coordinate
write logic we need, and it's not really related to the VPM read logic
other than the reuse of the use_count array.
