Also a very good point, I think we can skip this node generation if the boolean
value is not ambiguous. I don't want to squeeze this change into this NFC
commit, because I can easily imagine that skipping a superfluous `ExplodedNode`
could cause functional changes in some rare corner case. However, it would be
nice and not too difficult to fix this in a follow-up commit.
