      Revert "[runtime] Improve for-in performance" · a4235f00
      Aseem Garg authored 
      This reverts commit 8fa7f9ed.

Reason for revert: Speculating that this breaks GC stress

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
>

      Ujjwal Sharma authored 
      This increases the size of a DateFormat instance by a word to store
the bound format function.

The instance to be bound is stored on the context of this builtin function.
