Original change's description:
> zlib: inflate using wider loads and stores
>
> In inflate_fast() the output pointer always has plenty of room to write.
> This means that so long as the target is capable, wide un-aligned
> loads and stores can be used to transfer several bytes at once.
>
> When the reference distance is too short simply unroll the data a
> little to increase the distance. Patch by Simon Hosie.
>
> PNG decoding performance gains should be around 30-33%.
>
> BUG=697280
