Function _mm_maskz_dpbf16_ps

#[target_feature(enable = "avx512bf16", enable = "avx512vl")]
pub fn _mm_maskz_dpbf16_ps(k: __mmask8, src: __m128, a: __m128bh, b: __m128bh) -> __m128

Compute dot-product of BF16 (16-bit) floating-point pairs in a and b, accumulating the intermediate single-precision (32-bit) floating-point elements with elements in src, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
