That can be worked out from the debug_info and debug_loc without
requiring debug_line info. (not the instruction vs. function, but all
the rest).

Not that debuggers do know that, and not that it would be useful for
debugging... But I don't see a strong point to intentionally omit
them.

Just a thought...
