i965/fs: Add support for generating MADs.
Improves nexuiz performance 0.65% +/- .10% (n=5) on my gen6, and .39%
+/- .11% (n=10) on gen7. No statistically significant performance
difference on warsow (n=5, but only one shader has MADs).
v2: Add support for MADs in 16-wide by using compression control.
v3: Don't generate MADs when it will force an immediate to be moved to a temp.
(it's not clear whether this is a win or not, but it should result in less
questionable change to codegen compared to v2).
