  TryStatement : try Block Catch Finally

    Let B be the result of evaluating Block.
    If B.[[Type]] is throw, let C be CatchClauseEvaluation of Catch with argument B.[[Value]].
    Else, let C be B.
    Let F be the result of evaluating Finally.
    If F.[[Type]] is normal, set F to C.
    Return Completion(UpdateEmpty(F, undefined)).
