commit    948ef7cdc499b5226784a45ef1187ff554bf692a

    Exit early from pg_comp_crc32c_pmull for small inputs
    
    The vectorized path in commit fbc57f2bc had a side effect of putting
    more branches in the path taken for small inputs. To reduce risk
    of regressions, only proceed with the vectorized path if we can
    guarantee that the remaining input after the alignment preamble is
    greater than 64 bytes. That also allows removing length checks in
    the alignment preamble.
