Noah Goldstein c25eb94aed x86: Remove AVX512-BVMI2 instruction from strrchr-evex.S 
commit b412213eee
    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.
