Move bits/atomic.h to atomic-machine.h (bug 14912).

It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/atomic.h to atomic-machine.h to follow that
convention.

This is the only change in this series that needs to change the
filename rather than simply removing a directory level (because both
atomic.h and bits/atomic.h exist at present).

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).
