The warning still checks for those. The destructor check is unchanged.
The constructor check know also checks that the constructor is used, so
if the code can depend on its side effects, there is no warning.

On the firefox build the only case that is borderline with a false
positive is a template specialization where a variable is unused, but is
used in the general template.
