Merge restrictlist_selectivity into clauselist_selectivity by
teaching the latter to accept either RestrictInfo nodes or bare
clause expressions; and cache the selectivity result in the RestrictInfo
node when possible.  This extends the caching behavior of approx_selectivity
to many more contexts, and should reduce duplicate selectivity
calculations.
