I agree that the logic in there seems a bit odd. What is called
shouldEmitMoves should probably include all possible
reasons for printing the unwind tables. We should probably also use
uwtable to guard the emission of other table formats
as you propose.
The semantics uwtable is just "make sure it is possible to unwind past
this function". It doesn't include an...

It has to be an attribute because of LTO. You can LTO a file compiled
