  9. Let declaredFunctionNames be a new empty List.
  10. 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.
         ii. NOTE If there are multiple FunctionDeclarations for the same name,
             the last declaration is used.
         iii. Let fn be the sole element of the BoundNames of d.
         iv. If fn is not an element of declaredFunctionNames, then
             1. Let fnDefinable be ? envRec.CanDeclareGlobalFunction(fn).
             2. If fnDefinable is false, throw a TypeError exception.
             3. Append fn to declaredFunctionNames.
             4. Insert d as the first element of functionsToInitialize.

  17. For each production f in functionsToInitialize, do
      a. Let fn be the sole element of the BoundNames of f.
      b. Let fo be the result of performing InstantiateFunctionObject for f
         with argument env.
      c. Perform ? envRec.CreateGlobalFunctionBinding(fn, fo, false).

  8.1.1.4.16 CanDeclareGlobalFunction

  1. Let envRec be the global Environment Record for which the method was
     invoked.
  2. Let ObjRec be envRec.[[ObjectRecord]].
  3. Let globalObject be the binding object for ObjRec.
  4. Let existingProp be ? globalObject.[[GetOwnProperty]](N).
  5. If existingProp is undefined, return ? IsExtensible(globalObject).
