We're seeing intermittent failures in upstream bots. See: https://lab.llvm.org/buildbot/#/builders/139/builds/29185 https://lab.llvm.org/buildbot/#/builders/238/builds/295 This appears to be due to the unstable iteration order of DenseSet. Since we're trying to reduce a tree, it makes sense to attempt reductions from the top down. This also addresses post-review comments from @MatzeB.
