Enable the i586-optimized bcopy if the cpu is a "586" and option
I586_OPTIMIZED_BCOPY is configured.

Similarly for bzero/I586_OPTIMIZED_BZERO.

Fake 586's had better have a hardware FPU with non-broken exception
handling (we mask exceptions, but broken exception handling may trap
on the instructions that do the masking).  I guess this means that
the routines won't work on most 386's or FPUless 486's even when they
have a h/w FPU.
