Log message:
	Use multiple locations for hardware watchpoints.
	This eliminates the need to traverse value chain, doing
	various checks, in three different places.
	
	* breakpoint.h (struct bp_location): New fields
	lengths and watchpoint_type.
	(struct breakpoint): Remove the val_chain field.
	* breakpoint.c (is_hardware_watchpoint): New.
	(free_valchain): Remove.
	(update_watchpoint): New.
	(insert_bp_location): For hardware watchpoint, just
	directly insert it.
	(insert_breakpoints): Call update_watchpoint_locations
	on all watchpoints.  If we have failed to insert
	any location of a hardware watchpoint, remove all inserted
	locations.
	(remove_breakpoint): For hardware watchpoints, directly
	remove location.
	(watchpoints_triggered): Iterate over locations.
	(bpstat_stop_status): Use only first location of
	a resource watchpoint.
	(delete_breakpoint): Don't call free_valchain.
	(print_one_breakpoint): Don't print all
	locations for watchpoints.
	(breakpoint_re_set_one): Use update_watchpoint for
	watchpoints.
