pub unsafe fn _mm_maskz_alignr_epi64<const IMM8: i32>(
    k: u8, 
    a: __m128i, 
    b: __m128i
) -> __m128i

🔬 This is a nightly-only experimental API. (stdsimd)

This is supported with target feature avx512f,avx512vl only.

Concatenate a and b into a 32-byte immediate result, shift the result right by imm8 64-bit elements, and store the low 16 bytes (2 elements) in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
