    attribs: Don't crash on NULL TREE_TYPE in diag_attr_exclusions [PR11463=
4]=20=20=20

    The enumerator still doesn't have TREE_TYPE set but diag_attr_exclusion=
s=20=20=20=20
    assumes that all decls must have types.=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20
    I think it is better in something as unimportant as diag_attr_exclusion=
s=20=20=20=20
    to be more robust, if there is no type, it can just diagnose exclusions=
=20=20=20=20=20
    on the DECL_ATTRIBUTES, like for types it only diagnoses it on=20=20=20=
