* expr.c (int highest_label_pc_this_method,
	start_label_pc_this_method): New globals.
	(lookup_label): Add start_label_pc_this_method to pc for label, and
	update highest_label_pc_this_method.  This prevents conflicts between
	labels from different methods.
	* java-tree.h: Declare new globals.
	* jcf-parse.c (parse_class_file): If needed bump
	start_label_pc_this_method and reset highest_label_pc_this_method.
