#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm256_mask_permutevar_ps(src: __m256, k: __mmask8, a: __m256, b: __m256i) -> __m256

Shuffle single-precision (32-bit) floating-point elements in a within 128-bit lanes using the control in b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
