I don't follow how it works with a single `OpOperand*`. Can you elaborate a little more? In the data layout propagation case, there could be `(pack, reshape)`, `(reshape, pack)`, `(generic, pack)`, `(pack, generic)`, etc. I don't follow how to distinguish `(pack, reshape)` and `(reshape, pack)` cases in the approach.
