If a dtor has no interesting members, then it ends up being nothrow, which affects the generated IR.
Modify some tests to tolerate this difference between C++03 and C++11.

In C++11, a destructor without an explicit exception-spec gets an implicit exception-spec.
If the dtor has a body, the implicit exception-spec permits throwing exactly the set of types thrown by anything the dtor calls.  If the dtor doesn't have a body, use what would be the default dtor's body to determine the implicit exception-spec.  If there are no calls, the implicit exception-spec is nothrow.
