Factor out some of the code for updating old SCEVUnknown values, and extend it to handle the case where multiple RAUWs affect a single SCEVUnknown. Add a ScalarEvolution unittest to test for this situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109705 91177308-0d34-0410-b5e6-96231b3b80d8
