If we only flatten transfer ops but not their producers/consumers, we would end up with `vector.shape_cast` ops that won't be optimized away. The `vector.shape_cast` ops introduced by this pass should cancel out with the ones introduced by the transfer read/write flattening pass.

Oh I see the point, very good point!
