Jonathan Wakely 6c0c7fc623 libstdc++: Move atomic functions to libsupc++ [PR 96657] 
The changes for PR libstdc++/64735 mean that libsupc++ function might
now depend on the __exchange_and_add and __atomic_add functions defined
in config/cpu/*/atomicity.h which is not compiled into libsupc++. This
causes a link failure for some targets when trying to use libsupc++
without the rest of libstdc++.

This patch simply moves the definitions of those functions into
libsupc++ so that they are available there.

	PR libstdc++/96657
	* libsupc++/Makefile.am: Add atomicity.cc here.
