Jonathan Swinney 04904a0fff md5: add assembly implementation for aarch64 
This change improves md5 performance significantly by using a hand-optimized
assembly implementation of the inner loop of md5 calculation. The instructions
are carefully ordered to separate data dependencies as much as possible.

Test with:
$ openssl speed md5
