The original tests already include this: https://github.com/llvm/llvm-project/blob/9f2b4b6c787e0a143d34fcebae8267617fe9e73b/libcxx/test/std/input.output/filesystems/class.path/path.member/path.compare.pass.cpp#L144
But it doesn't cover the different slash as root dir test case, so I add it: https://github.com/llvm/llvm-project/blob/9f2b4b6c787e0a143d34fcebae8267617fe9e73b/libcxx/test/std/input.output/filesystems/class.path/path.member/path.compare.pass.cpp#L81
