1. Convert the tstate saved in the pcb to a pstate and test for PSTATE_PEF
   to determine if a process is using floating point. in order to avoid
   sign extending a 13 bit immediate.
2. We don't need to context switch cwp anymore, it is better to just
   fiddle the save tstate on return from traps.  See exception.s 1.10
   and 1.12.
3. Completely remove pcb_cwp.
4. Implement vmapbuf, vunmapbuf and vm_fault_quick.  Completely remove
   TODOs from vm_machdep.c (yay!).
