RE: SIMD optimization for list_sort

Hi Alvaro and John,

Thanks for your feedback and discussions here.

At this time, I'd like to withdraw the commitfest item [1]. The original developer who proposed the patch is no longer
atIntel, and the x86-simd-sort library's future is also uncertain. Due to ongoing changes on our end at this time, we
won'tbe able to support this work going forward.  :- (
