#[target_feature(enable = "avx512vpopcntdq", enable = "avx512vl")]
pub const fn _mm_maskz_popcnt_epi64(k: __mmask8, a: __m128i) -> __m128iFor each packed 64-bit integer maps the value to the number of logical 1 bits.
Uses the writemask in k - elements are zeroed in the result if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
