Provide PDEP and PEXT instructions
The PDEP (parallel bit deposit) and PEXT (parallel bit extract) instructions are super cool and could be very naturally expressed in GHC as:
packedBitDeposit :: Word# -> Word# -> Word#
packedBitExtract :: Word# -> Word# -> Word#I requesting that these be added to GHC.Prim (or more accurately, I'm requesting approval for these be added to GHC.Prim, by me or by any other interested party, possibly at a more distant point in the future).
