Can we make the number of inputs always be 3 for this operator? If
FLAG_vector_stores are off we can just pass undefined to the operator and remove
it in generic lowering. But having different number of inputs depending on a
flag seems brittle.

Good idea. In fact, we can just pass the feedback vector too. Done.

Likewise for always having 4 inputs.
