	(cp_parser_parenthesized_expression_list): Add non_constant_p.
	(cp_parser_new_placement): Adjust call to
	cp_parser_parenthesized_expression_list.
	(cp_parser_direct_new_declarator): Likewise.
	(cp_parser_conditional_expression): Remove.
	(cp_parser_constant_expression): Parse an assignment-expression,
	not a conditional-expression.
	(cp_parser_simple_declaration): Resolve expression/declaration
	ambiguity more quickly.
	(cp_parser_mem_initializer): Adjust call to
	cp_parser_parenthesized_expression_list.
	(cp_parser_init_declarator): Keep track of whether or not the
	initializer is a constant-expression.
	(cp_parser_initializer): Add non_constant_p parameter.
	(cp_parser_initializer_clause): Likewise.

	(cp_parser_attribute_list): Adjust call to

	* pt.c (tsubst_decl): Copy
	DECL_INITIALIZED_BY_CONSTANT_EXPRESSION_P.
	(tsubst_expr): Tweak use of DECL_PRETTY_FUNCTION_P.
	* semantics.c (finish_id_expression): Use
