Original issue's description:
> [runtime] Migrate Object.getOwnPropertyNames to C++.
>
> The Object.getOwnPropertyNames method always calls into C++ anyway,
> so there's no point in having the JavaScript wrapper around at all.
>
> Drive-by-fix: Inline GetOwnEnumerablePropertyNames into its single
> call site.
