pan/bi: Add dual texture fusing pass

Bifrost supports a special "dual texture" instruction, sampling from two
textures at once at the same coordinate. Each subinstruction is highly
restricted (a subset of TEXS_2D); together, they are represented by TEXC
with a special dual texture operation descriptor. Add an optimization
pass to fuse these instructions.
