	of PLUS_EXPR for pointers.
	* tree-vect-transform.c (vect_create_addr_base_for_vector_ref):
	Likewise.
	* tree-inline.c (estimate_num_insns_1): Handle
	POINTER_PLUS_EXPR.
	* tree-object-size.c (plus_expr_object_size): Handle
	POINTER_PLUS_EXPR instead of PLUS_EXPR.  Removing all the extra
	code which is trying to figure out which side is a pointer and 
	is the index.
	(check_for_plus_in_loops_1): Likewise.
	(check_for_plus_in_loops): Likewise.
	* c-common.c (pointer_int_sum): Create a
	POINTER_PLUS_EXPR instead of PLUS_EXPR for pointers.
	* tree-ssa-structalias.c (handle_ptr_arith): Handle
	only POINTER_PLUS_EXPR.  Removing all the extra
	code which is trying to figure out which side is a pointer and 
	is the index.
	* tree-cfg.c (verify_expr): Add extra checking for pointers and
	PLUS_EXPR and MINUS_EXPR.
	Also add checking to make sure the operands of POINTER_PLUS_EXPR
	are correct.
