Function `_mm256_mask_fmsub_ps`

#[target_feature(enable = "avx512f", enable = "avx512vl")]
pub const fn _mm256_mask_fmsub_ps(a: __m256, k: __mmask8, b: __m256, c: __m256) -> __m256

Multiply packed single-precision (32-bit) floating-point elements in a and b, subtract packed elements in c from the intermediate result, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
