	* include/atomic.h: Define atomic_compare_and_exchange_val_acq,
	atomic_compare_and_exchange_val_rel,
	atomic_compare_and_exchange_bool_acq, and

	atomic_compare_and_exchange_acq and atomic_compare_and_exchange_rel.
	* sysdeps/i386/i486/bits/atomic.h: Define
	__arch_compare_and_exchange_val_*_acq instead of
