+ 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.
