Original change's description:
> [VM runtime] Support Smi instances in type test cache.
> 
> This adds SubtypeTestCache-based optimizations for type tests against
>       * dst_type = FutureOr<T> (when T=int/num)
>       * dst_type = T (when T = FutureOr<int/num>)
>

> Handle instantiated void in type tests (along with dynamic and Object).
