Original issue's description:
> [js] Avoid %_ClassOf for collection builtins.
>
> The collection builtins (Map, Set, WeakMap, WeakSet) are still written
> in JavaScript and make heavy use of %_ClassOf, which is kind of
> expensive compared to a simple instance type check. Change that to use
> simple instance type checks instead.
