pub fn _mm256_maskz_permutex2var_epi32(k: __mmask8, a: __m256i, idx: __m256i, b: __m256i) -> __m256iShuffle 32-bit integers in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
