Add a minor 'cas' atomic optimization on sparc.
* sysdeps/sparc/sparc32/sparcv9/bits/atomic.h (__arch_compare_and_exchange_val_32_acq): Use %g0 as second argument of CAS if possible. * sysdeps/sparc/sparc64/bits/atomic.h (__arch_compare_and_exchange_val_32_acq): Likewise. (__arch_compare_and_exchange_val_64_acq): Likewise.
