This is a possible way to get LTO to not drop debug information with
rL358069 <https://reviews.llvm.org/rL358069>. It marks native object files generated by LTO as live if
they contain global symbols (which means these symbols are used by
other TUs or exported) so that even if MarkLive cannot see a reference
to the object, its debug information is preserved.
