	* class.c (add_method): Just check processing_template_decl to
	determine whether or not we are within a template.
	* decl2.c (maybe_retrofit_in_chrg): Likewise.
	* init.c (decl_constant_value): Check the type of the declaration,
	not TREE_READONLY.
	* name-lookup.c (maybe_push_to_top_level): Rename to ...
	(push_to_top_level): ... this.
	* name-lookup.h (maybe_push_to_top_level): Do not declare it.
	* pt.c (push_template_decl_real): Reorder condition for speed.
	(convert_template_argument): Use dependency-checking functions in
	place of uses_template_parms.
	(lookup_template_class): Avoid calling uses_template_parms more
	than once.
	(uses_template_parms): Reimplement, using dependency-checking
	functions.
	(instantiate_class_template): Use push_to_top_level, not
	maybe_push_to_top_level.
	(type_unification_real): Simplify.
	(type_dependent_expression_p): Handle OFFSET_REFs and
	TEMPLATE_DECLs.
	(any_dependent_template_arguments_p): Handle multiple levels of
	template argument.
	* semantics.c (expand_or_defer_fn): Do not check
	uses_template_parms for template instantiations.
	* typeck.c (comptypes): Avoid calling cp_type_quals.
