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.
