Chandler Carruth aea315a631 [LoopInfo] Add helper methods to compute two useful orderings of the ... loops in a function. These are relatively confusing to talk about and compute correctly so it seems really good to write down their implementation in one place. I've replaced one place we needed this in the loop PM infrastructure and I have another place in a pending patch that wants it. We can't quite use this for the core loop PM walk because there we're sometimes working on a sub-forest. I'll add the expected unittests before committing this but wanted to make sure folks were happy with these names / comments. Credit goes to Richard Smith for the idea for naming the order where siblings are in reverse program order but the tree traversal remains preorder.
