jay: swap predication/acc pass order

Browse source 
Lets us use more accumulators, I think this is well motivated. Saw this in a
test shader.

Totals from 242 (9.14% of 2647) affected shaders:
Instrs: 1365060 -> 1365035 (-0.00%); split: -0.00%, +0.00%
CodeSize: 20678592 -> 20680096 (+0.01%); split: -0.01%, +0.02%
