I would incline to declare this an user error. GCC does not control the meaning
of all of the user specified sections and thus I would say that user is either
required to use constructor/destructor attributes or "used" attribute.

For sure we can add magic and make cgraph_finalize_function or so to drop an
attribute implicitly.

Note that constructor/destructor attributes are different from used
attribute+named section. We know how to optimize away ctors/dtors without side
effects etc. So it would be better to convert such code to an dedicated
attribute.
