These patterns follow FoldMemRefAliasOps which is further refactored for reuse. In the process, fix FoldMemRefAliasOps handling of strides for vector.transfer ops which was previously incorrect. These opt-in patterns generalize the existing canonicalizations on vector.transfer ops. In the future the blanket canonicalizations will be retired. They are kept for now to minimize porting disruptions. Differential Revision: https://reviews.llvm.org/D146624
