i965/fs: Add an optimization pass to remove redundant flags movs.

We generate steaming piles of these for the centroid workaround, and this
quickly cleans them up.

total instructions in shared programs: 1591228 -> 1590047 (-0.07%)
instructions in affected programs:     26111 -> 24930 (-4.52%)
GAINED:                                0
LOST:                                  0

(Improved apps are l4d2, csgo, and dolphin)
