Decorate __exchange_and_add and __atomic_add

[Jan Hubicka]

Hi,
these are quite verbose...
Tested on x86_64-linux, OK?
	* include/ext/atomicity.h
	(__exchange_and_add, __atomic_add): Mark throw ().
	* config/os/aix/atomicity.h
	* config/os/aix/atomicity.h
	* config/os/irix/atomicity.h
	* config/cpu/cris/atomicity.h

	* config/cpu/hppa/atomicity.h
	* config/cpu/sparc/atomicity.h

	* config/cpu/i486/atomicity.h
	* config/cpu/sh/atomicity.h
	* config/cpu/generic/atomicity_mutex/atomicity.h
	* config/cpu/generic/atomicity_builtins/atomicity.h
	(__exchange_and_add, __atomic_add): Mark throw ().
