    x86/Intel: address quoted-symbol related FIXMEs
    
    If in a "word ptr <address>" or alike construct the "ptr" part is
    double-quoted, it shouldn't be recognized as the specific keyword we're
    looking for (just like we don't recognize double-quoted operator or
    register names anymore). Be careful though to tell closing from opening
    double-quotes, as a quoted symbol may follow right afterwards.
