    Speed up software CRC-32 computation by a factor of 1.5 to 3. · f8719f5a
    Mark Adler authored 
    Use the interleaved method of Kadatch and Jenkins in order to make
use of pipelined instructions through multiple ALUs in a single
core. This also speeds up and simplifies the combination of CRCs,
and updates the functions to pre-calculate and use an operator for
CRC combination.
