* pt.c (finish_member_template_decl): If the type in a TYPE_DECL
is error_mark_node, return an error early.
(find_parameter_packs_r): Pass the pointer set along to recursive
calls of cp_walk_subtrees; don't try to manage the pointer set
ourselves.
(uses_parameter_packs): Pass the pointer set to cp_walk_tree.
(make_pack_expansion): Ditto.
(check_for_bare_parameter_packs): Ditto. Also, don't bother taking
a second pass through the tree with find_parameter_packs_r; that
second pass no longer does anything.
(push_template_decl_real): If we have an erroneous declaration,
set its type to error_mark_node before returning an error.
