Bryce Denney 565fa8ea8e - another speed boost: when not using SMP, use 
BX_CPU_C bx_cpu;
     BX_MEM_C bx_mem;
  and when more than one processor, use
     BX_CPU_C    *bx_cpu_array[BX_SMP_PROCESSORS];
     BX_MEM_C    *bx_mem_array[BX_ADDRESS_SPACES];
  The changeover is controlled by BX_SMP_PROCESSORS, but there are only
  a few code changes since nearly all code uses the BX_CPU(n) and BX_MEM(n)
  macros.
- This turns out to make a 10% speed difference!  With this revision,
  the CVS version now gets 95% of the performance of the 3/25/2000
  snapshot, which I've been using as my baseline.
