x86: Disable non-temporal memset on Skylake Server
The original commit enabling non-temporal memset on Skylake Server had erroneous benchmarks (actually done on ICX). Further benchmarks indicate non-temporal stores may in fact by a regression on Skylake Server. This commit may be over-cautious in some cases, but should avoid any regressions for 2.40. Tested using qemu on all x86_64 cpu arch supported by both qemu + GLIBC. Reviewed-by: DJ Delorie <dj@redhat.com> Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
