Used by the routine at Handle_Sabreman_Falling.
Makes Sabreman tumble (see Handle_Sabreman_Tumbling) when he is knocked about while he jumps or falls. The type of the object is set to 18 which is the first frame of the tumbling Sabreman.
The x position is then limited so that he does not tumble into the wall: it is kept below C0 when the room has a wall on the right, and below E8 when it does not.
