Reapply the new LoopStrengthReduction code, with compile time and bug fixes, and with improved heuristics for analyzing foreign-loop addrecs. This change also flattens IVUsers, eliminating the stride-oriented groupings, which makes it easier to work with. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95975 91177308-0d34-0410-b5e6-96231b3b80d8
