Function _mm256_maskz_permutex2var_ps

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm256_maskz_permutex2var_ps(k: __mmask8, a: __m256, idx: __m256i, b: __m256) -> __m256

Shuffle single-precision (32-bit) floating-point elements 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).
