i965/fs: Constant-fold immediates in src0 of SEL instructions.
This is like what we do for add/mul, but we have to invert the
predicate to choose the other source instead.
This removes 5 extra moves of constants in nexuiz shaders. No
statistically significant performance difference on my Sandybridge
laptop (n=5).
