        Two of the toJSNewlyCreated() optimisations in r34141 were never
        reached due to a generator bug and missing IDL attribute.

        Fix header generation to provide the necessary toJSNewlyCreated()
        overloads.

        Patch includes a related build fix by Jan Michael Alonzo.
