  -----------
  [mlir][memref] Tighten verification of memref.reinterpret_cast

We allow the omission of a map in memref.reinterpret_cast under the assumption,
that the cast might cast to an identity layout. This change adds verification
that the static knowledge that is present in the reinterpret_cast supports
this assumption.
