Tom Lane cff60f2dfa Avoid creating PlaceHolderVars immediately within PlaceHolderVars. ...

Such a construction is useless since the lower PlaceHolderVar is already
nullable; no need to make it more so.  Noted while pursuing bug #6154.

This is just a minor planner efficiency improvement, since the final plan
will come out the same anyway after PHVs are flattened.  So not worth the
risk of back-patching.
