os: treat non-symlink reparse points as irregular files Prior to this change (as of CL 143578), our stat function attempted to resolve all reparse points as if they were symlinks. This results in an additional call to CreateFile when statting a symlink file: we use CreateFile once to obtain the reparse tag and check whether the file is actually a symlink, and if it is we call CreateFile again without FILE_FLAG_OPEN_REPARSE_POINT to stat the link target. Fortunately, since symlinks are rare on Windows that overhead shouldn't be a big deal in practice. Fixes #42919.
