SmallPtrSet would work as well; whether it matters depends on the
sorts of lookups you're trying to do.  As far as I know, there isn't
anything builtin, though; none of the existing passes have any use for
such a datastructure.

Again, I would suggest looking at the algorithm and checking whether
you really need to explicitly construct the graph.
