IsExist returns a boolean indicating whether its argument is known to report
that a file or directory already exists. It is satisfied by [ErrExist] as
well as some syscall errors.
This function predates [errors.Is]. It only supports errors returned by
the os package. New code should use errors.Is(err, fs.ErrExist).
