Allow basicaa to walk through geps with identical indices in parallel, allowing it to decide that P/Q must alias if A/B must alias in things like: P = gep A, 0, i, 1 Q = gep B, 0, i, 1 This allows GVN to delete 62 more instructions out of 403.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60820 91177308-0d34-0410-b5e6-96231b3b80d8
