- Move setting curlwp back to cpu_switchto(). Necessary because if
  curlwp is made a register variable, we may also need to keep a
  copy in struct cpu_info for other CPUs to inspect. Okay yamt@.
- Clearing ci_need_resched is now done in mi_switch().

- Tidy up slightly: remove pointless #ifdefs, make function descriptions
  consistent, remove checks for options that were removed 4+ years ago, ...
- Don't reload %cr0 or check for RAS if switching to a kthread.
- Don't try dropping the ipl using "movl $IPL_SCHED,CPUVAR(ILEVEL)". Causes
  deadlocks because the later drop of priority (possibly by mi_switch) can
  fail to notice pending IPIs. Just leave the level at IPL_IPI (for a very
  short time) at let it be dropped in mi_switch(). Spotted by yamt@.

cpu_switchto:

- Replace cli/sti with raising the priority level to IPL_IPI.
- Don't reload %cr0 unless necessary.

Improves timings for a pthread condvar benchmark I have by a further 45%
on a dual core system. Reviewed by yamt@.
