This reverts commit d4e3b9e8bc.

Reason for revert: will reland with fixes

Original change's description:
> impl gather8/gather16 with gather32
> 
> This is our quick path to JIT small gathers.
> 
> The idea is roughly,
> 
>    const uint32_t* ptr32 = ptr8;
>    uint32_t abcd = ptr32[ix/4];
>    switch (ix & 3) {
>      case 3: return (abcd >> 24)       ;
>      case 2: return (abcd >> 16) & 0xff;
>      case 1: return (abcd >>  8) & 0xff;
>      case 0: return (abcd      ) & 0xff;
>    }
> 
> With the idea that if we may load a given byte,
> we should also be allowed to load the four byte
> aligned word that byte falls within.
