#[target_feature(enable = "avx512f")]
pub fn _mm512_mask_cvtusepi64_epi16(src: __m128i, k: __mmask8, a: __m512i) -> __m128i

Convert packed unsigned 64-bit integers in a to packed unsigned 16-bit integers with unsigned saturation, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
