	* tree.h (get_object_or_type_alignment): Remove.
	* builtins.c (get_object_alignment_2): New function copied from
	get_object_alignment_1.  Take extra argument to indicate whether
	we take the address of EXP.  Rework to use type alignment information
	if not, and return whether the result is an approximation or not.
	(get_object_alignment_1): Wrap around get_object_alignment_2.
	(get_pointer_alignment_1): Call get_object_alignment_2 indicating
	we take the address.
	(get_object_or_type_alignment): Remove.
	* expr.c (expand_assignment): Call get_object_alignment.
	(expand_expr_real_1): Likewise.
