MFC i386/i386/machdep.c 1.520 and rearrange the original -stable code a
bit to look more like -current.  Adds support for the 'machdep.cpu_idle_hlt'
sysctl on SMP machines.  The default is still 0 for SMP since -stable has the
same non-fatal run-queue race that current has (a 1-tick run latency if the
race is lost).  Setting the value to 1 will save power.

Tested: my Smart-UPS 1400 reports 81.2% utilization with cpu_idle_hlt
enabled and 81.9% with it disabled on one box, and 83.8% utilization with it
disabled on three boxes.
