This is going to need to be modified to allow transitions out of
FINAL_STATUS_WINDOW_OPENER. For example, there may be a window.open() for the
prerendered link followed by a normal <a href=""> transition where the
PrerenderContents is used.

As discussed we will throw away the prerendered page.

   DCHECK(final_status >= FINAL_STATUS_USED && final_status < FINAL_STATUS_MAX);
   DCHECK(final_status_ == FINAL_STATUS_MAX ||
          final_status_ == FINAL_STATUS_CONTROL_GROUP);
 
   // Don't override final_status_ if it's FINAL_STATUS_CONTROL_GROUP,
   // otherwise data will be collected in the Prerender.FinalStatus histogram.
   if (final_status_ == FINAL_STATUS_CONTROL_GROUP)
     return;
