Function _mm256_mask_testn_epi8_mask

#[target_feature(enable = "avx512bw", enable = "avx512vl")]
pub const fn _mm256_mask_testn_epi8_mask(k: __mmask32, a: __m256i, b: __m256i) -> __mmask32

Compute the bitwise NAND of packed 8-bit integers in a and b, producing intermediate 8-bit values, and set the corresponding bit in result mask k (subject to writemask k) if the intermediate value is zero.
