Adjust overly strict Assert 3373c7155 changed how we determine EquivalenceClasses for relations and added an Assert to ensure all relations mentioned in each EC's ec_relids was a RELOPT_BASEREL. However, the join removal code may remove a LEFT JOIN and since it does not clean up EC members belonging to the removed relations it can leave RELOPT_DEADREL rels in ec_relids.
Fix this by adjusting the Assert to allow RELOPT_DEADREL rels too.
