This patch documents rust-embedded#583 adds failing loom tests to exercise rust-embedded#583 hoping that a future algorithm change can make them pass. The tests are ran in CI but their results is ignored for now as they fail. Ideally the `loom` tests will cover more usage of `mpmc::Queue` in the future and also cover `spsc`.
