[PATCH] D23466: ADT: Remove UB in ilist (and use a circular linked list)

[Duncan P. N. Exon Smith via llvm-commits]

dexonsmith added a comment.

Another direction I plan to pursue rather quickly is "fixing" reverse iterators, so that rbegin().getNodePtr()==&*rbegin().  This allows much simpler logic when erasing elements during a reverse traversal.
