Summary: Without this, this command $ llvm-run llc -stop-after machine-cp -o - <( echo '' ) outputs an error, because we close stdout twice -- once when closing the file opened for "-o", and again when closing outs(). Also clarify in the outs() definition that you can't ever call it if you want to open your own raw_fd_ostream on stdout.
