----------------
Is this safe? What happens if the destructor for the variable is a template,
and instantiating that template results in a reference to a device function? Eg:
```
template<typename T> __device__ void f() {}
template<typename T> struct A {
~A() { f<<<>>>(); }
};
A a;
```

InHD inhd;
- Out out; // expected-error{{no matching constructor for initialization of
'Out'}}
+ Out out;
OutD outd;
----------------
I don't think we should accept this -- only functions that are defaulted on
their first declaration should get special treatment. Instead of checking for
`isDefaulted()` above, you should check for `!isUserProvided()` instead.
