Original change's description:
> Infer the language mode instead of passing it as a parameter to builtins
> 
> It is better to infer the language mode from the context and the closure
> instead of getting it from the feedback vector. This will allow us to use
> some of these builtins even when feedback vectors are not allocated.
> Language mode is only needed to decide if we need to throw an exception
> when a store fails. This is on a slow path and hence deriving the language
> mode is not on critical path.
