Remove atomic_compare_and_exchange_bool_rel.
atomic_compare_and_exchange_bool_rel and catomic_compare_and_exchange_bool_rel are removed and replaced with the new C11-like atomic_compare_exchange_weak_release. The concurrent code in nscd/cache.c has not been reviewed yet, so this patch does not add detailed comments. * nscd/cache.c (cache_add): Use new C11-like atomic operation instead of atomic_compare_and_exchange_bool_rel. * nptl/pthread_mutex_unlock.c (__pthread_mutex_unlock_full): Likewise. * include/atomic.h (atomic_compare_and_exchange_bool_rel, catomic_compare_and_exchange_bool_rel): Remove. * sysdeps/aarch64/atomic-machine.h (atomic_compare_and_exchange_bool_rel): Likewise. * sysdeps/alpha/atomic-machine.h (atomic_compare_and_exchange_bool_rel): Likewise. * sysdeps/arm/atomic-machine.h (atomic_compare_and_exchange_bool_rel): Likewise. * sysdeps/mips/atomic-machine.h (atomic_compare_and_exchange_bool_rel): Likewise. * sysdeps/tile/atomic-machine.h (atomic_compare_and_exchange_bool_rel): Likewise.
