Ian Romanick 52c7df1643 i965/fs: Merge CMP and SEL into CSEL on Gen8+ 
v2: Fix several problems handling inverted predicates.  Add a much
bigger comment around the BRW_CONDITIONAL_NZ case.

v3: Allow uniforms and shader inputs as sources for the original SEL and
CMP instructions.  This enables a LOT more shaders to receive CSEL
merging (5816 vs 8564 on SKL).

v4: Report progress.

Broadwell and Skylake had similar results. (Broadwell shown)
