I would simply really emit the debug info to the accompaning object file
and make sure it gets copied over to the final executable. Of course
we'd need to associate lto1s decls with the correct dwarf die for the
decls/types. But reading in the dwarf tree and looking up dies should
be "easily" possible, no? ;)
