When we suppress linkage names, for a non-inlined subprogram the name
can still be found in the object-file symbol table, because we have
the code address of the subprogram.  This is not the case for an
inlined subprogram, so we still want to emit the linkage name in the
DWARF.  Put this on the abstract-origin DIE because it's common to all
inlined instances.
