pub fn _mm256_maskz_shuffle_epi8(k: __mmask32, a: __m256i, b: __m256i) -> __m256iShuffle packed 8-bit integers in a according to shuffle control mask in the corresponding 8-bit element of b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
