I'm not super familiar with this pattern, but this change makes sense to me, thanks for working on this!

How about unrolling along the K _and_ some other dim? Could you add a test? That doesn't have to capture all the generated ops - just the relationship between `smmla` Ops (to demonstrate that the accumulator is only re-used where it makes sense).
