And on Ironlake, we gain a bunch of SIMD16 programs since we would
have otherwise bailed since we were visiting an if-statement.
total instructions in shared programs: 4381625 -> 4378980 (-0.06%)
instructions in affected programs: 426790 -> 424145 (-0.62%)
GAINED: 186
LOST: 0
All the programs gained are in Anomaly-2.
