This variable is supposed to indicate whether we are doing a first or last index reduction. The problem is that by defining it outside the loop it becomes dependent on the order we visit the USE/DEFs. In the given example, the loop isn't PEELED, but we visit the early exit uses first. This then sets the boolean to true and it can't get to false again. So when we visit the main exit we still treat it as an early exit for that SSA name. This cleans it up and renames the variables to something that's hopefully clearer to their intention. Bootstrapped Regtested on aarch64-none-linux-gnu and x86_64-pc-linux-gnu no issues. Ok for master?
