Michael Zolotukhin 3efc2c1480 Add CFG Simplification pass after Loop Unswitching. ... Loop unswitching produces conditional branches with constant condition, and it's beneficial for later passes to clean this up with simplify-cfg. We do this after the second invocation of loop-unswitch, but not after the first one. Not doing so might cause problem for passes like LoopUnroll, whose estimate of loop body size would be less accurate.
