    aarch64: Enable `-M notes' by default
    
    We already print other instruction comments, such as condition code
    aliases, by default.  The `-M no-notes' option has been available in
    Binutils for over 7 years, so if anyone does need the notes to be
    disabled then they can do so explicitly.
