Are the other debugging backends not interested at all in USING_DECLs ? 

The way debug info is generated for USING_DECLs is that
handle_using_decl (via cp_emit_debug_info_for_using) asks the backend to
generate debug info for the DECLs the USING_DECL resolves to, basically.
AIUI, the backend is not supposed to handle the USING_DECL himself.

That seems to be only used for namespace- or function-scope using-declarations; we don't do anything for class-scope using-declarations currently. DWARF2 is interested in them, but that seems like a separate chunk of work, so for now let's just set DECL_IGNORED_P like Dodji suggested.
