Add libc++ to link XRay test cases if libc++ is used to build CLANG
Summary: When libc++ is used to build CLANG, its XRay libraries libclang_rt.xray-*.a have dependencies on libc++. Therefore, libc++ is needed to link and run XRay test cases. For Linux -rpath is also needed to specify where to load libc++. This change sets macro LLVM_LIBCXX_USED to 1 if libc++ is actually used in the build. XRay tests then check the flag and add -L<llvm_shlib_dir> -lc++ and -Wl,-rpath=<llvm_shlib_dir> if needed.
