That could work, though I'm then a bit confused why `BuildMI` requires both the
`MBB` and `Iter` values. My guess is that it has something to do with when
`Iter` is at the end of the list?
If it's okay, I'd like to keep it like this for the time being. If it's
possible to safely get the MBB from the iterator, then we should probably
consider adding a `BuildMI` which takes only an iterator instead of both.
