Function _mm_maskz_fnmadd_pd

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub const fn _mm_maskz_fnmadd_pd(k: __mmask8, a: __m128d, b: __m128d, c: __m128d) -> __m128d

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