    Completion value when iteration completes due to expression value

    IterationStatement : while ( Expression ) Statement

    1. Let V = undefined.
    2. Repeat
       a. Let exprRef be the result of evaluating Expression.
       b. Let exprValue be GetValue(exprRef).
       c. ReturnIfAbrupt(exprValue).
       d. If ToBoolean(exprValue) is false, return NormalCompletion(V).
       e. Let stmt be the result of evaluating Statement.
       f. If LoopContinues (stmt, labelSet) is false, return
          Completion(UpdateEmpty(stmt, V)).
       g. If stmt.[[value]] is not empty, let V = stmt.[[value]].
