	* call.c (build_op_delete_call): Test user-visible type against
	size_type_node, instead of against the internal type, sizetype.
	* class.c (type_requires_array_cookie): Likewise.
	* mangle.c (write_builtin_type) <INTEGER_TYPE>: Remove special
	handling of TYPE_IS_SIZETYPE.
	* typeck.c (type_after_usual_arithmetic_conversions): Remove
	special case handling of TYPE_IS_SIZETYPE.
	(comptypes): Likewise.
