Returns the correct completion values of try-catch-finally(Normal) in functions
info: |
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)).
