[Mlir-commits] [mlir] [MLIR][Tensor, MemRef] Fold expand_shape and collapse_shape if identity (PR #80658)

Allowing identity expansions/collapsion (and folding them) makes sense to me. Interestingly, I have seen this pattern (disallowing "identity" ops) in other places. E.g., certain "cast" ops that do not change the type fail verification.
