It looks like we cannot simply swap the code and mode in rtx_def, the code may

Ugh. We really just need to fix this code. It assumes particular
structure layouts and that's just wrong/dumb.
So I think think the first step is to fix up this crap code in
var-tracking. That should be a patch unto itself. Then we'd have the
structure changes as a separate change.
