We have this wonderful thing called an optimizer---maybe we should consider calling it?
Slightly improves the vertex shaders in Shadowrun Returns, which uses ARB_vertex_program and ARB_fragment_program: total instructions in shared programs: 117131 -> 117016 (-0.10%) instructions in affected programs: 6771 -> 6656 (-1.70%) No fragment programs were helped. Presumably, we don't see any benefits for FS because our FS backend has a much better optimizer than our vec4 backend.
