    docs: Add @cindex for some attributes
    
    While looking for the access attribute,
    I tried to find it via the concept index but it was
    missing. This patch fixes that and adds one for
    interrupt/interrupt_handler too.
    
    Committed as obvious after building the HTML docs
    and looking at the resulting concept index page.
    
    gcc/ChangeLog:
    
            * doc/extend.texi (access attribute): Add
            cindex for it.
            (interrupt/interrupt_handler attribute):
            Likewise.
