bf946c3ec3 C++: remove comments about Java implies predicates
The Java guards library includes a set of "implies" predicates to handle
short-circuiting conditionals. C++ handles those in IR generation, so
dominance on the IR produces correct results for controlling blocks.

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. |

da73a033e5 C++: Restore exists(getBlock()) in AV Rule 82
I removed this condition in #362, thinking it was covered by the new
conditions on return statements, but it turns out it wasn't in at least
the following cases.

1. Assignment operators that are deleted or marked private in order to
   make them inaccessible.
2. Templates whose body was not extracted.

While some of these results are technically valid, they are not nearly
as interesting as the results that this query was designed to produce.

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.

bfa4c30784 C++: Improve performance of ExprEvaluator::getFunctionValue.
Changes the `forex` range to join on both `this` (the current `ExprEvaluator`) and `ret` (the expected function return value),
so that we look at the relevant return values rather than all interesting functions.
