Alyssa Rosenzweig a4d3a29647 pan/bi: Enable dual texture fusing pass 
Everything is in place for it now -- ship it! Our Bifrost cycle model is
coarse, so take the shader-db results with a massive spoonful of salt:

Defined partially in software, partially in hardware.

Blend shaders

Fragment

Anything live during BLEND must respect blend shader registers.

R0 - R3: preloaded (message #0) R4 - R7: preloaded (message #1) R57 - R63: preloaded (various)

R0 - R15: general purpose (full threads) R48 - R63: general purpose (full threads)
