Yes, I don't think we should change anything if it's converted to an absolute path.

Only if the `-fdebug-compilation-dir` is not given or is an absolute path, the path in `/Fo` will be converted to absolute path. Users can avoid the path being converted to absolute path by passing a relative path to `-fdebug-compilation-dir`, just like what we do in chrome build (`-fdebug-compilation-dir=.`).

Added a test.
