On second thought, I think we should just leave this alone.
scanned_tuples is closely tied to tupcount_pages, so it's a little
confusing to pull one out and not the other.  And we can't pull
tupcount_pages out of LVRelStats because lazy_cleanup_index needs it.
The current situation isn't doing any harm, so I'm not seeing much
point in changing it.
