Function `_mm512_maskz_mul_pd`

#[target_feature(enable = "avx512f")]
pub const fn _mm512_maskz_mul_pd(k: __mmask8, a: __m512d, b: __m512d) -> __m512d

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