Function `_mm_mask_fnmsub_pd`

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

Multiply packed double-precision (64-bit) floating-point elements in a and b, subtract packed elements in c from the negated intermediate result, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
