ScalarEvolution: Introduce SCEVSDivision and SCEVUDivision It turns out that not all users of SCEVDivision want the same signedness. Let the users determine which operation they'd like by explicitly choosing SCEVUDivision or SCEVSDivision. findArrayDimensions and computeAccessFunctions will use SCEVSDivision while HowFarToZero will use SCEVUDivision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222104 91177308-0d34-0410-b5e6-96231b3b80d8
