MINOR: threads: Implement __ha_barrier_atomic*. Implement __ha_barrier functions to be used when trying to protect data modified by atomic operations (except when using HA_ATOMIC_STORE). On intel, atomic operations either use the LOCK prefix and xchg, and both atc as full barrier, so there's no need to add an extra barrier.
