Log message:
    Use Params, rather than run-time-modified Const nodes, to handle
    sublink results and COPY's domain constraint checking.  A Const that
    isn't really constant is just a Bad Idea(tm).  Remove hacks in
    parse_coerce and other places that were needed because of the former
    klugery.
