Dan Gohman 35738ac150 Re-apply 70645, converting ScalarEvolution to use ... CallbackVH, with fixes. allUsesReplacedWith need to walk the def-use chains and invalidate all users of a value that is replaced. SCEVs of users need to be recalcualted even if the new value is equivalent. Also, make forgetLoopPHIs walk def-use chains, since any SCEV that depends on a PHI should be recalculated when more information about that PHI becomes available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70927 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-04 22:30:44 +00:00
