Some patterns in the file only works for tensors. E.g., `SimplifyPackToExpandShape` always replaces it with `tensor.expand_shape` op. I think you need to revisit all the patterns and bail out when the pack/unpack op does not have pure tensor semantics.

We can bail out for all the cases and relax patterns for memref later. IMO, we should not leave it as a crash or unhandled failure when we add the memref semantics to pack/unpack ops.
