ah, good catch, I'm thinking of this op like a Vector dialect op and of course that's not the case. I'll remove this, it's not a problem because in the pass I'm explicitly checking all but the last outer product in a chain have single use and erasing them. Marking this as pure means cse would do that for us, but it's not necessary.
