The idea of the original order was that you'd dead code eliminate accesses
to push constants. But I've never seen a case of that (nor has
shader-db), while we frequently see sparse accesses of large constant
arrays that would overflow into pull constants.
Cuts pull constant use on csgo, serious sam, planeshift, and the cave:
total instructions in shared programs: 1695103 -> 1688795 (-0.37%)
instructions in affected programs: 92024 -> 85716 (-6.85%)
GAINED: 339
LOST: 0
