x86: Remove AVX512-BVMI2 instruction from strrchr-evex.S
commit b412213eee0afa3b51dfe92b736dfc7c981309f5 Author: Noah Goldstein <goldstein.w.n@gmail.com> Date: Tue Oct 18 17:44:07 2022 -0700 x86: Optimize strrchr-evex.S and implement with VMM headers Added `vpcompress{b|d}` to the page-cross logic with is an AVX512-VBMI2 instruction. This is not supported on SKX. Since the page-cross logic is relatively cold and the benefit is minimal revert the page-cross case back to the old logic which is supported on SKX. Tested on x86-64.
