John Baldwin fb1faf2082 Tweak the low-level MI SMP code some: 
- Use cpu_spinwait() in the spin loops in stop_cpus(), restart_cpus(), and
  smp_rendezvous_action().
- Remove unneeded acq memory barriers in stop_cpus(), restart_cpus(), and
  smp_rendezvous_action().
- Add an additional synch point in smp_rendezvous() to ensure that all the
  CPUs will always see an up-to-date value of smp_rv_setup_func.
