    docs: Fix inconsistent example predicate name
    
    It is unclear why the example C function was renamed to
    `commutative_integer_operator` as part of ec8e098d in 2004, while the
    text and the example md were both left as `commutative_operator`. The
    latter name appears to be more accurate, so revert the 2004 change.
    
    gcc/ChangeLog:
    
            * doc/md.texi: Fix inconsistent example name.
