i965/fs: Allow immediates in MAD and LRP instructions.

And then the opt_combine_constants() pass will pull them out into
registers. This will allow us to do some algebraic optimizations on MAD
and LRP.

total instructions in shared programs: 5946656 -> 5931320 (-0.26%)
instructions in affected programs:     778247 -> 762911 (-1.97%)
