Perhaps we can drop them to 0 in free lang data? It indicates the implicit typedef that let's you say 'S' instead of 'struct S' without writing 'typedef struct S S' yourself. dwarf2out.c uses this information in TYPE_DECL_IS_STUB and is_redundant_typedef, so we can't clear it until after debug info generation.
