I agree with @huixie90 here. This is not fixing the broken atomic support, but we have other GH issues tracking that. This is merely making the CI green again for some configurations that are currently failing.

The bottom line is that atomic's support for `long double` is broken all around and we added tests for it, which now obviously fail. We should probably have punted on adding the tests for `long double` until they actually worked on all platforms, and this is what this PR is doing.
