These are things reachable from BINFO_VIRTUALS, DECL_ABSTRACT_ORIGIN,
etc.  We then try to merge to share them again on the reader side, but
fail to find an assembler name for them (which is the only thing we
can use to merge them).  One could argue that these should be cleared
out, though BINFO_VIRTUALS are used for obj_type_ref folding.
