I'd hope not...  The out-of-line instance and all inlined instances
should be pointing to the same abstract origin.  If the out-of-line
instance gets emitted first, *maybe* what you suggest can happen,
because we haven't yet noticed there are inline instances?  But 
that's not how the DWARF is supposed to look.
