URL: https://github.com/llvm/llvm-project/commit/b9da488ad729a6604439d1b5e456330bab9321bd DIFF: https://github.com/llvm/llvm-project/commit/b9da488ad729a6604439d1b5e456330bab9321bd.diff LOG: [SimplifyCFG] Don't actually take DomTreeUpdater unless we intend to maintain DomTree validity This guards against unintentional mistakes like the one i just fixed in previous commit.
