Jake Burkholder 05f6ee66ea Implement preemptive scheduling of hardware interrupt threads. 
- If possible, context switch to the thread directly in sched_ithd(),
  rather than triggering a delayed ast reschedule.

- Disable interrupts while restoring fpu state in the trap handler,
  in order to ensure that we are not preempted in the middle, which
  could cause migration to another cpu.
