  Log:
   - On my Pentium4-M laptop, invalpg takes ~1100 cycles if the page is found in
     the TLB and ~1600 if it is not.  Therefore, it is more effecient to
     invalidate the TLB after operations that use CMAP rather than before.
   - So that the tlb is invalidated prior to switching off of a processor, we
     must change the switchin functions to switchout functions.
   - Remove td_switchout from the thread and move it to the x86 pcb.
   - Move the code that calls switchout into swtch.s.  These changes make this
     optimization truely x86 specific.
