Fix Object::Clone()'s pre-fence barrier.

Pass in a pre-fence barrier object that sets in the array length
instead of setting it after returning from AllocObject().

Fix another potential bug due to the wrong default pre-fence barrier
parameter value. Since this appears error-prone, removed the default
parameter value and make it an explicit parameter.

Fix another potential moving GC bug due to a lack of a SirtRef.
