    c: Add _Countof operator [PR117025]

broke gcc build on RHEL 9 when building texi files:

gcc/doc/extend.texi:6: node `C Extensions' lacks menu item for
`_Countof' despite being its Up target

Fixed by adding the missing menu entires.

Ok for trunk?

Thx,
Haochen

gcc/ChangeLog:

        * doc/extend.texi (C Extensions): Add missing menu items.
