Revert "gather8/16 JIT support"

This reverts commit 54659e51bccc106b67ba36d5e91cac457d84b99e.

Reason for revert: ASAN

Original change's description:
> gather8/16 JIT support
> 
> The basic strategy is one at a time, inserting 8- or 16-bit values
> into an Xmm register, then expanding to 32-bit in a Ymm at the end
> using vpmovzx{b,w}d instructions.
> 
> Somewhat annoyingly we can only pull indices from an Xmm register,
> so we grab the first four then shift down the top before the rest.
> 
> Added a unit test to get coverage where the indices are reused and
> not consumed directly by the gather instruction.  It's an important
> case, needing to find another register for accum that can't just be
> dst(), but there's no natural coverage of that anywhere.
