toplev.c (flag_evaluation_order): New global variable.

	* toplev.c (flag_evaluation_order): New global variable.
	* flags.h (flag_evaluation_order): Prototype here.
	* expr.c (expand_operands): If we need to preserve observable
	evaluation order, protect exp1 from clobbering exp0's result.

	* java/lang.c (java_init_options): Set flag_evaluation_order.
	* java/expr.c (force_evaluation_order): Don't attempt to force
	evaluation order of binary operations using save_expr.
	* java/parse.y (java_complete_lhs): No longer need to call
	force_evaluation_order when constructing binary operators.
