Ian Romanick af07141b33 intel/compiler: More peephole_select for pre-Gen6
No shader-db changes on any Gen6+ platform.

All of the shaders with cycles hurt by more than ~2% are from Master of
Orion.  All of the shaders have instructions helped.  It looks like the
pass enables some control flow to be converted to bcsels, then the
scheduler does dumb things.  These are new shaders (just added before
doing this shader-db run), so there's probably some low-hanging fruit.
