Rather than making CvGV refcounted if the CV is anon, decide based on
whether the GV pointed to by CvGV holds a reference back to us. Normally
these two will be equivalent, but this way is more robust if people are
doing weird things.
Also spotted an error with cv_clone not clearing the CVf_CVGV_RC flag on
the newly cloned cv. This shouldn't normally matter as it will get set
shortly anyway, but best to keep things logically correct.
