Close this revision because D58170 <https://reviews.llvm.org/D58170> is landed. D58170 <https://reviews.llvm.org/D58170> solves the problem this patch trying to resolve.
It also improves the implementation of deduplication, which only takes 0.31s when it deduplicates and validates updates when optimizing `clang-5.0.0.bc`, while this patch takes 14 seconds to snapshot the CFG.
