    libcody: Remove nop asm
    
    This asm was a useful place for gdb to drop a breakpoint and make it
    clear where you were when debugging.  I took a punt that 'surely every
    arch has a nop instruction'. Well, no, some apparently have nops with
    operands (what, do nothing harder? :)

            * fatal.cc (HCF): Remove nop breakpoint lander.
