Alyssa Rosenzweig abe5b06a99 pan/bi: Use lower_frag_coord_to_pixel_coord 
Instead of vendoring the logic. This has a side benefit of letting NIR
optimize the generated code a bit.

Bifrost compiler

Register file

Defined partially in software, partially in hardware.

Blend shaders

R0 - R3: input (color #0) R4 - R7: input (color #1) R8 - R15: general purpose R48: return address

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)

R32 - R47: general purpose (half threads, or v6)
