Agreed, that makes a lot of sense. We could do the same for the `add` and `sub`
operations too since they are equivalent to a conversion followed by the fp
operation as well. It looks like we are missing intrinsics some variants of
these base operations currently (`fma` and `add` with `.sat` and all of `sub`)
so I've just added those and used this pattern to lower to the mixed precision
instructions.
Please take a look, thanks!
