i965/fs: Allow copy propagation on uniforms.
This is a big win for savage2, hon and yofrankie. 62 new programs for
savage2/hon get 16-wide mode, along with one for humus demos and two
for tropics. Even a few shaders from tropics see reductions of 15% or
more.
total instructions in shared programs: 216536 -> 207353 (-4.24%)
instructions in affected programs: 123941 -> 114758 (-7.41%)
In benchmarking Tropics, only a .040% +/- 034% performance improvement
was observed (n=90). Rather disappointing, but I was primarily
motivated to do this patch by a regression in the number of 16-wide
shaders compiled after a GRF texturing on IVB patch I'm working on.
Hopefully this helps avoid that regression.
