The patch below adds configuration options for Centaur/IDT winchips,
setting the correct cache alignment options, and enabling 3dnow!
memory copy routines on Winchip 2A and above.

The Winchip-C6 option sets the same flags as the AMD-K6, but I feel
that giving it a seperate option will prevent confusion.

regards,
