[RC5] 999 to 1000 blocks and P5: MMX vs Classic

As far as I know, there is no MMX core for RC5-72.  Back in the
days of RC5-64 there were a lot more Pentium 1 MMX's around, but
now there probably isn't much demand for an MMX core.


Isn't it still a good idea to develop one? Increased efficiencies of older
machines can only help, and the code should be relatively (?) easy to
transpose from 64 to 72.
