[Mesa-dev] [PATCH 16.1/24] i965/vec4: Fix cmod propagation not to propagate non-identity cmod into CMP(N).

The conditional mod of these instructions determines the semantics of the comparison itself (rather than being evaluated based on the result of the instruction as is usually the case for most other instructions that allow conditional mods), so it's in general not legal to propagate a conditional
