I would suggest lowering dot with dimx=2 to mul+add or dp2add, according to the shader model, in the same lowering pass. Possibly, although I don't know that we want to spend too much effort on matching native instructions exactly. Yep, now I think it would be fine to always lower to mul+add for SM1 (if dimx=2), as long as we keep the `FIXME` specifically for `ps_3_0`, in case it ever matters.
