I The real issue here is that if `d0` is unit-dim in one operand, any use of `d0` to access any other dim has to be unit-dim as well (by constructions). Really we should be calling these linalg ops illegal.
I think we have a way to make sure the dimensions match for Linalg ops. Will try to find those.
