9382c9d528 C++: Regression tests for AV Rule 82 
Without the last commit, this addition to the test gives the following
results:

```
+| AV Rule 82.cpp:176:14:176:22 | operator= | Assignment operator in class Forgivable does not return a reference to *this. |
+| AV Rule 82.cpp:181:14:181:22 | operator= | Assignment operator in class Forgivable does not return a reference to *this. |

0c796de831 C++: Fork AV Rule 78 into NonVirtualDestructorInBaseClass 
AV Rule 78 has proved too noisy for use on lgtm.com. However, if we make the rule less noisy by, say, allowing a protected destructor to be non-virtual, we're no longer actually enforcing AV Rule 78. Instead, I've copied AV Rule 78 into NonVirtualDestructorInBaseClass.ql, given the new query the `@id` that AV Rule 78 had, and given AV Rule 78 a new JSF-specific `@id`. The new rule allows non-public non-virtual destructors, which is the problem originally reported by an lgtm.com user.

eef8719a40 C++: Fix AV Rule 85 
We have to be careful to avoid giving alerts to functions that might be
correctly defined, but we can't see the definition as it wasn't
instantiated.
