LGTM, but please look into making these be folds instead of canonicalization patterns. That should also make the code simpler since the folding infra will give you the folded attributes pre-canned without having to do as much getDefiningOp<ConstShapeOp>().


This is technically a fold, right?

I think we are using true and successful witness interchangeably, should we just pick one?


Same comments re-formatting.

Replace with folding and handle non-const but equal inputs.
