This was broken out of the first tree-vrp refactoring patch. This patch
just moves two classes to earlier points in the file.
Richi approved this as part of the larger patch. But since I had it
pulled out, I'm going to commit it individually. I'm posting the patch
here for archival purposes.
Bootstrapped and regression tested on x86_64.
Jeff
