[PATCH] D77341: [DomTree] Replace ChildrenGetter with GraphTraits over GraphDiff.

[Alina Sbirlea via Phabricator via cfe-commits]

Yes. The difference in perf in instructions and cycles count is due to reversing the update order.
I'm still not seeing meaningful changes in wall-time even with the update order reversed, but reliable wall-time testing is hard.

I do have changes that

- drop the GraphTraits usage entirely in favor of the getChildren() method in GraphDiff
- refactor the hashmaps in GraphDiff

but I plan to send those separately.
