This is a reland of 0896599f with a fix for
failing layout test.

Original change's description:
> Change SetProperty/SetSuperProperty to infer language mode when possible
>
> In most cases, the language mode can be inferred from the closure and
> the context. Computing the language mode instead of passing it around
> simplifies the ICs and will make it possible to go towards lazily
> allocating feedback vectors. Currently ICs obtain the language mode from
> the feedback vectors and with lazy feedback allocation we may not always
> have feedback vectors. Since computing language mode is a bit expensive
> we want to defer it as far as possible.
>
> In Array builtins and other builtins like Reflect.Set we need to force a
> language mode when setting the properties. To support these cases the
> SetProperty methods allow the language mode to be overridden when needed.
>
> This is a first cl in a series of cls, that will defer the language mode
> computation further and remove language mode where it is not needed.
>
> BUG: v8:8580
