  Log Message:
  -----------
  [HashRecognize] Remove byte-multiple trip count requirement (#210086)

The newly added carryless-multiply CRC loop optimization (#203405) does
not require a byte-multiple trip count unlike the Sarwate method which
was previously implemented. Loosen this requirement in HashRecognize and
reapply it in `optimizeCRCLoop`.
