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
