            Make ScopeChainNode GC allocated
            https://bugs.webkit.org/show_bug.cgi?id=55283
    
            Simplify lifetime and other issues with the scopechain
            by making it gc allocated.  This allows us to simplify
            function exit and unwinding, as well as making the
            current iterative refcounting go away.
