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.

C++: Stricter loop-variant check
...
The `loopVariant` predicate in `ComparisonWithWiderType.ql` is intended
to identify loop counters, but it was too much of a stretch to apply it
to any subexpression of the small side of the comparison.
This change fixes two false positives on arvidn/libtorrent and many
others seen in the wild (on Linux, CoreCLR, ffmpeg, ...).
