This change can improve md5 performance by using a hand-optimized
assembly implementation of the inner loop of md5 calculation.
This implementation refered to md5-x86_64.pl and made more effort
to reorder instructions for separating data dependencies as much
as possible.
Test with:
$ openssl speed md5
