This should handle fusions that have a single output. If there's more than one output (like some of the topk stuff) then the one in the middle won't currently be checked. It should be possible to handle that as well by allocating and comparing multiple results, but I didn't do that yet.
I added a couple missing ops that I hit running test-backend-ops.
Indentation makes this diff look bigger than it really is, I'd suggest reviewing it in a better diff tool.
