Note that the UNROLL option makes the 'inner' des loop unroll all 16 rounds
instead of the default 4.
RISC1 and RISC2 are 2 alternatives for the inner loop and
PTR means to use pointers arithmetic instead of arrays.

Notes.
[1] For the ultra sparc, SunC 4.0 
    cc -xtarget=ultra -xarch=v8plus -Xa -xO5, running 'des_opts'
    gives a speed of 344,000 des/s while 'speed' gives 459,000 des/s.
    I'll record the higher since it is coming from the library but it
    is all rather weird.
[2] Similar to the ultra sparc ([1]), 181,000 for 'des_opts' vs 175,000.
[3] I was unable to get access to this machine when it was not heavily loaded.
    As such, my timing program was never able to get more that %30 of the CPU.
    This would cause the program to give much lower speed numbers because
    it would be 'fighting' to stay in the cache with the other CPU burning
    processes.
