Sorry for the followup.
This doesn't have to be part of this patch of course, but IWBN if "i reg"
included a note next to register values obtained via heuristics.
[such values could have a flag set]
It could even be just a general warning printed by "i reg" in
non-inner-most frames, but it feels like the above shouldn't be too hard.
