Andrew Trick b85da1c369 Added a SimplifyIndVar utility to simplify induction variable users ... based on ScalarEvolution without changing the induction variable phis. This utility is the main tool of IndVarSimplifyPass, but the pass also restructures induction variables in strange ways that are sensitive to pass ordering. This provides a way for other loop passes to simplify new uses of induction variables created during transformation. The utility may be used by any pass that preserves ScalarEvolution. Soon LoopUnroll will use it. The net effect in this checkin is to cleanup the IndVarSimplify pass by factoring out the SimplifyIndVar algorithm into a standalone utility. llvm-svn: 137197		2011-08-10 03:46:27 +00:00
