This is a code cleanup patch. No functionality change is introduced.

Previously, CFLGraphBuilder maintained 5 auxiliary structures in addition to the CFLGraph under construction. Among those five structures, the escaped value set and the external value set were irreplaceable when they were first introduced, but now their use cases can be completely covered by InstantiatedAttrs. We could simplify CFLGraphBuilder (as well as its clients) by removing those two sets.
