Available on (x86 or x86-64) and target feature avx512bitalg and x86 only.
Expand description

Considers the input b as packed 64-bit integers and c as packed 8-bit integers. Then groups 8 8-bit values from cas indices into the bits of the corresponding 64-bit integer. It then selects these bits and packs them into the output.
