Add a new control flow simplifier.
Run it in the dead code elimination phase, as it relates to
creating dead branches.
From 0.04 to 0.07% less code size framework/gms/docs/fb (70K saved on fb)
3%-5% runtime performance improvements on Richards/DeltaBlue/Ritz.
Compile-time is mixed, so in the noise (from 2% slower to 1% faster).
