Log message:
    Further tweaking of parsetree & plantree representation of SubLinks.
    Simplify SubLink by storing just a List of operator OIDs, instead of
    a list of incomplete OpExprs --- that was a bizarre and bulky choice,
    with no redeeming social value since we have to build new OpExprs
    anyway when forming the plan tree.
