Always call finalizer for stack classes. Checking for the number of destructors of the class type is not sufficient: we may be holding a derived class with a destructor. Fixes: run/auto_07

// idouble

module typeinfo1.ti_idouble;

private import typeinfo1.ti_double;

class TypeInfo_p : TypeInfo_d
{
    char[] toString() { return "idouble"; }
}
