Add atomics support for 32-bit PPC.
This was originally submitted as a patch on the Google Code issue
tracker, but the original author didn't submit a pull request. They did,
however, give permission for somebody else to do so. I cleaned up a few
things myself and am now submitting it.
I can't find any record of what the original patch was, but there is a
copy of the discussion at
<https://groups.google.com/forum/#!topic/protobuf/SMwF5fYHIi0>;.
Fixes google/protobuf#581
