Avoid stat call to determine is_directory if possible

On Linux and OS X, we can determine if an entry obtained through a readdir()
call is a directory without also having to stat it. This can save a
significant number of syscalls. The performance increase isn't dramatic, but
it could be on some platforms (e.g. Cygwin) so it shouldn't hurt to use this
unconditionally where supported.
