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

#include "gen/llvm.h"
#include "ir/irmodule.h"

IrModule::IrModule(Module* module)
{
    M = module;
    dwarfCompileUnit = NULL;
}

IrModule::~IrModule()
{
}
