Function _mm256_maskz_scalef_pd

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub fn _mm256_maskz_scalef_pd(k: __mmask8, a: __m256d, b: __m256d) -> __m256d

Scale the packed double-precision (64-bit) floating-point elements in a using values from b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
