This revision adds a conservative canonicalization pattern for MemRefCastOp that are typically inserted during ViewOp and SubViewOp canonicalization.
Ideally such canonicalizations would propagate the type to consumers but this is not a local behavior. As a consequence MemRefCastOp are introduced to keep type compatibility but need to be cleaned up later, in the case where more dynamic behavior than necessary is introduced.
