Alina Sbirlea 40a0781572 [LoadStoreVectorizer] Enable vectorization of stores in the presence of an aliasing load ... Summary: The "getVectorizablePrefix" method would give up if it found an aliasing load for a store chain. In practice, the aliasing load can be treated as a memory barrier and all stores that precede it are a valid vectorizable prefix. Issue found by volkan in D26962. Testcase is a pruned version of the one in the original patch.
