603a3af19b C++: Treat implicit end of body of non-void function as Unreached 
When the extractor can't prove that control flow will never reach the end of a non-`void`-returning function without reaching an explicit `return` statement, it inserts an implicit `return` without an operand. If control actually reaches this point, the behavior is undefined.

We were previously generating invalid IR for these implicit `return` statements, because the lack of an operand meant that there was no definition of the return value variable along that path. Instead, I've changed the IR generation to emit an `Unreached` instruction for the implicit `return`. This ensures that we don't create a control flow edge from the end of the body to the function epilogue.

The change to the range analysis test avoids having that test depend on the previous bad IR behavior, while still preserving the original spirit of the test.

58366b19e9 C++: Path explanations in the last two queries 
For some reason I thought that these two queries were special because
they manipulate `SecurityOptions` to change the taint-tracking sources.
It turns out it was just the opposite: the queries used to be special
because they invalidated the cache for the `tainted` predicate, but that
predicate is no longer used, so these queries are no longer special.
