  Modified files:
    sys/powerpc/powerpc  fpu.c genassym.c swtch.S trap.c 
  Log:
  Enable the FPU on first use per-thread and save state across context
  switches. Not as lazy as it could be. Changing FPU state with sigcontext
  still TODO.
  
  fpu.c - convert some asm to inline C, and macroize fpu loads/stores
  swtch.S - call out to save/restore fpu routines
  trap.c - always call enable_fpu, since this shouldn't be called once
           the FPU has been enabled for a thread
  genassym.c - define for pcb fpu flag
