- 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.
