 - Use the correct test in the ipi bitmask handler for IPI_PREEMPT so that
   we actually issue preemptions.
 - Remove the #ifdef IPI_PREEMPTION so it is always compiled in.  Leave
   the option which optionally enables support in sched_4bsd.  sched_ule.c
   will soon use this functionality as a run time rather than compile time
   option.
 - Compare against the idlethread rather than the priority.  There are some
   idle prio tasks that we can preempt.

Discussed with:	ups
Tested on:	i386, amd64
