libc++ actually has a test suite that can be used on other compilers and it
looks like someone's been running it against gcc.  You will find tests for
those features in libcxx/test/.

See
https://releases.llvm.org/5.0.0/projects/libcxx/docs/TestingLibcxx.html#cmdoption-lit-arg-use_system_cxx_lib
and
