Subject: atomic: Add include guards to the implementation headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes them pass standalone compilation tests. Previously,
they included atomic.h which included themselves again, leading to
double definitions.
