i965/fs: Add empirically-determined instruction latencies for gen7.
v2: Actually switch on the other math instructions mentioned in the comment. v3: Add timing data for textureSize(), and clean up some long comment lines. Testing shader_time of fs16 shaders on a few frames of various apps: nexuiz improved by 2.9% +/- 1.5% (n=10) no difference on GLB2.5 (n=36, outliers removed) no difference on GLB2.7 (n=25) etqw improved by 2.6% +/- 2.2% (n=25) no difference on lightsmark (n=25) Acked-by: Kenneth Graunke <[email protected]>
