Emulating avx-512 intrinsics in Miri
Recently we've started work on using more avx512 features in zlib-rs. The avx512 family of target features provides SIMD intrinsics that use 512-bit vectors (double the size of avx2, which uses 256-bit vectors). These wider intrinsics can speed up certain algorithms dramatically.
