Very old submission (from 2000) of UltraSPARC assembler DES implementation.

It was not accepted because code is not PIC, too UltraSPARC-specific when
it doesn't have to and 32-bit only. I'm committing the original version
mostly for reference purposes. 64, PIC, blended CPU tune-up follows shortly.
