Jason, please do you know what is meaning of DECL_ARTIFICIAL on class type
names? 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 andis_redundant_typedef, so we can't clear it until after debug infogeneration.
