    1. Let newTarget be GetNewTarget().
    2. If newTarget is undefined, throw a ReferenceError exception.
    3. Let func be GetSuperConstructor().
    4. ReturnIfAbrupt(func).
    5. Let argList be ArgumentListEvaluation of Arguments.

    12.3.6.1 Runtime Semantics: ArgumentListEvaluation

    ArgumentList : ArgumentList , ... AssignmentExpression

    1. Let precedingArgs be the result of evaluating ArgumentList.
    2. Let spreadRef be the result of evaluating AssignmentExpression.
    3. Let iterator be GetIterator(GetValue(spreadRef) ).
    4. ReturnIfAbrupt(iterator).
    5. Repeat
       a. Let next be IteratorStep(iterator).
       b. ReturnIfAbrupt(next).
       c. If next is false, return precedingArgs.
