Available on (x86 or x86-64) and target feature `avx512cd` and x86 only.
Expand description

Test each 64-bit element of a for equality with all other elements in a closer to the least significant bit using writemask k (elements are copied from src when the corresponding mask bit is not set). Each element’s comparison forms a zero extended bit vector in dst.
