Jonas Jensen 19435e07a1 C++: Fix join order in CommentedOutCode ...

After the recent inlining of `unresolveElement`, the join order in
`CommentedOutCode` became a problem. The join orderer was tempted to
join the two `hasLocationInfo` calls first because they had one column
in common. With this commit, they have no columns in common. It follows
from the other predicates in the same file that this column would be the
same, so there is no need to assert it in this predicate and risk that
the join orderer uses that information.

On Wireshark, the `CommentBlock::hasLocationInfo` predicate goes from
taking 2m2s to taking 180ms. The query produces the same 7,448 alerts.
