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 `c`as indices into the bits of the corresponding 64-bit integer. It then selects these bits and packs them into the output.

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.
