class.c (finish_struct): If we're a local class in a template function, add a TAG_DEFN.

        * class.c (finish_struct): If we're a local class in a template
        function, add a TAG_DEFN.
        * pt.c (lookup_template_class): If this is a local class in a
        template function, call pushtag.
        (tsubst_expr, case TAG_DEFN): Handle classes, too.

        Emit debug info with the vtable.
        * search.c (maybe_suppress_debug_info): New function...
        * class.c (finish_struct_1): ...split out from here.
        * cp-tree.h: Declare it.
        * decl2.c (finish_vtable_vardecl): Override TYPE_DECL_SUPPRESS_DEBUG
        if we're writing out the vtable.
        * decl.c, search.c (dfs_debug_mark, dfs_debug_unmarked_p,
        note_debug_info_needed): #if 0 out.
