Improve atomic locking for ARM.
[BZ #15640]
* sysdeps/arm/bits/atomic.h (atomic_exchange_acq, atomic_exchange_rel)
(atomic_compare_and_exchange_bool_acq)
(atomic_compare_and_exchange_val_acq)
(atomic_compare_and_exchange_bool_rel)
(atomic_compare_and_exchange_val_rel): Use __atomic_exchange_n and
__atomic_compare_exchange_n builtins when GCC supports them.
