	(i386_dr_low_get_control): Likewise.
	(i386_dr_low_get_status): Likewise.
	(i386_get_debug_register_length): Likewise.
	* i386-nat.c (i386_dr_low_can_set_addr): Now in i386-nat.h.
	(i386_dr_low_set_addr): Likewise.
	(i386_dr_low_get_addr): Likewise.
	(i386_dr_low_can_set_control): Likewise.
	(i386_dr_low_set_control): Likewise.
	(i386_dr_low_get_control): Likewise.
