    8. For each d in varDeclarations, in reverse list order do
       a. If d is neither a VariableDeclaration or a ForBinding, then
          i. Assert: d is either a FunctionDeclaration or a
             GeneratorDeclaration.

        b. Let fo be the result of performing InstantiateFunctionObject for f
           with argument lexEnv.
