jhb dabf0d0c4f - Place the gcc memory barrier hint in the right place in the 80386 version
of atomic_store_rel().
- Use the 80386 versions of atomic_load_acq() and atomic_store_rel() that
  do not use serializing instructions on all UP kernels since a UP machine
  does need to synchronize with other CPUs.  This trims lots of cycles from
  spin locks on UP kernels among other things.
