* csu/tst-atomic.c (do_test): Add some new
atomic_compare_and_exchange_val_acq, atomic_add_zero,
atomic_compare_and_exchange_bool_acq and atomic_add_negative tests.
* include/atomic.h (atomic_add_negative, atomic_add_zero):
Prefix local variable so that it doesn't clash with the one
in atomic_exchange_and_add.
* sysdeps/ia64/bits/atomic.h (atomic_exchange): Fix for long/void *
pointers.
(atomic_exchange_and_add): Implement using __sync_fetch_and_add_?i.
* sysdeps/powerpc/bits/atomic.h (atomic_exchange_and_add): Force
value into register.
* sysdeps/s390/bits/atomic.h (__arch_compare_and_exchange_val_64_acq):
Cast newval to long.
* sysdeps/x86_64/bits/atomic.h
(__arch_compare_and_exchange_val_64_acq): Cast newval and oldval to
long.
(atomic_exchange): Cast newvalue to long if sizeof == 8.
(atomic_exchange_and_add): Cast value to long if sizeof == 8.
(atomic_add, atomic_add_negative, atomic_add_zero): Likewise.
(atomic_bit_set): Shift 1L up in all cases to shut up warnings.
