Jingyue Wu ec3cfb00dc [DependenceAnalysis] Allow subscripts of different types ... Summary: Several places in DependenceAnalysis assumes both SCEVs in a subscript pair share the same integer type. For instance, isKnownPredicate calls SE->getMinusSCEV(X, Y) which asserts X and Y share the same type. However, DependenceAnalysis fails to ensure this assumption when producing a subscript pair, causing tests such as NonCanonicalizedSubscript to crash. With this patch, DependenceAnalysis runs unifySubscriptType before producing any subscript pair, ensuring the assumption. Test Plan: Added NonCanonicalizedSubscript.ll on which DependenceAnalysis before the fix crashed because subscripts have different types.
