This just removes the usage of llvm::reverse and llvm::seq. That makes it harder to handle the empty case correctly and so I've also added a test there. This is just a shot in the dark at what might be behind the buildbot failures. I can't reproduce any issues locally including with ASan... I feel like I'm missing something... llvm-svn: 290954
