During the compact IDs optimization pass, the result IDs of some basic blocks can change. In spite of this, GetPreservedAnalyses indicated that the CFG was preserved. But the CFG relies on the basic blocks having the same IDs. Simply removing this flag resolves the issue by preventing the CFG check. Also Removes combinators and namemap preserved analyses from compact IDs pass.
