 Especially if we order texture results collection after other texture setup, this could be a big win (which would be hard to achieve post-register-allocation, when there are more dependencies).  See vc4-qir-sched.
 
-* Improve the pairing instruction scheduler.
-
-We could pair some cases with the PM bit set in only one of the instructions.

-* Blend in ARGB8888 instead of vec4.
-
-This would take about 1/4 the instructions.  However, we need to retain the float path because you want the improved precision for sRGB rendering.  See vc4-blend for WIP.
-
-* Handle vertex attribute size overrides in NIR.
-
-emit_vertex_input() currently handles things like making the .w coordinate of a vertex attribute be 1 when only xyz are passed in, and QIR optimizations aren't doing as well on that as they could.  Making a NIR pass to do this transformation would fix some silly math that occurs.

 * Copy propagate VPM reads into their usage if only used once.
 
 * Reorder fragment shader varyings so we can interpolate directly into texture coordinate setup?
