This series implements a vec4 equivalent to fs_cmod_propagation optimization.
The last two commits are not really needed for the optimization, are just
nice-to-have (imho) that I added while implementing the optimization.
Alejandro Piñeiro (5):
i965/vec4: nir_emit_if doesn't need to predicate based on all the
channels
i965/vec4: adding vec4_cmod_propagation optimization
i965/vec4: Add unit tests for cmod propagation pass.
i965/vec4: use a custom envvar to decide to print the assembly on
test_vec4_cmod_propagation
i965/vec4: print predicate control at brw_vec4 dump_instruction
