f69dad8c53 Walk back the optimization from check-in [cc458317bd77046c] that tries to 
reuse the same ephemeral cursor of a list subquery when that subquery is
reused, as it does not work in cases where the list subquery is used both
for lookups and for scans.

767bc8de8e Defer generating WHERE clause constraints for a RIGHT JOIN until after the 
ON-clause processing for the RIGHT JOIN has done its own row elimination.
This fixes and incorrect output from some RIGHT JOINs that was identified
by [forum:/forumpost/41cc3851d864c5e6|forum post 41cc3851d864c5e6].
