  Modified:    sys/i386/i386  identcpu.c
  Log:
  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.
