David Rowley c34605daed Fixup some misusages of bms_num_members() 
It's a bit inefficient to test if a Bitmapset is empty by counting all the
members and seeing if that number is zero. It's much better just to use
bms_is_empty().  Likewise for checking if there are at least two members,
just use bms_membership(), which does not need to do anything more after
finding two members.
