      E.g., "ToWeakHeapObject" was misleading, since it didn't convert to a weak heap
object, instead returned a weakly pointed heap object. Change the function names
(in this case, to "GetHeapObjectIfWeak") to reflect this.

Also make casts explicit, if a MaybeObject is an Object, we can call cast<Object>().

      Reland "[runtime] Improve for-in performance" · 827e6d12
      Camillo Bruni authored 
      This is a reland of 8fa7f9ed

Original change's description:
> [runtime] Improve for-in performance
> 
> - Add fast-path String conversion for Smi (which is the most common case)
>   This improves for-in by ~10% on non-initialized enum-caches
> - Don't use the NumberStringCache for large indices to not overflow the cache
>   during key collection. This improves worst-case performance by ~2.5x
> - Drop number_to_string_native and number_to_string_runtime counters
>
