#[target_feature(enable = "avx512vbmi2")]
pub unsafe fn _mm512_mask_expandloadu_epi8(src: __m512i, k: __mmask64, mem_addr: *const i8) -> __m512i

Load contiguous active 8-bit integers from unaligned memory at mem_addr (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
