On Windows, running unit tests by directly invoking `llvm-lit.py` (e.g. `python3 llvm-lit.py clang/test/Unit`) may create a folder named `%SystemDrive%` in the current working directory. This appears to happen because `lit.cfg.py` in `clang/test/Unit` does not propagate the `SystemDrive` environment variable.
