Implement the D "cpu" variable, which returns curcpu.  I have chosen not
to follow the example of OpenSolaris and its descendants, which implemented
cpu as an inline that took a value out of curthread.  At certain points in
the FreeBSD scheduler curthread->td_oncpu will no longer be valid (in
particukar, just before the thread gets descheduled) so instead I have
implemented this as its own built-in variable.
