The C++20-specific tests for <atomic> in libstdc++ were almost identical to the C++0x tests. Now that all tests can run for any -std option, and run with -std=gnu++20 by default, the C++20 tests are redundant. The C++20-specific parts are merged into the C++0x tests, and the C++20 tests are removed to reduce duplication.
