This feature is equivalent to `CCACHE_BASEDIR` and enables cache reuse across directories. This is needed because some absolute paths can end up in the preprocessed output via `__FILE__` macros or other debugging mechanisms. This causes cache misses even though the code is otherwise identical. When `CLANG_TIDY_CACHE_BASEDIR`/`base_dir` is set, we replace absolute paths that match that base prefix with relative paths in the preprocessed output. Additionally, we need to pass the `-P` flag to the preprocessor to avoid linemarker comments that indicate which bit of the output came from which header path.

This causes a bug that is fixed in #17. The file is not closed before calling os.Remove at line 110, which results in an error.
