[PATCH] D49679: [DebugInfo] Have custom DWARFDie:: reverse_iterator

[Pavel Labath via Phabricator via llvm-commits]

labath added a comment.

What's the reason for not specializing std::reverse_iterator? AFAIK, that is officially permitted by the standard.

This way somebody can still construct a `std::reverse_iterator<DWARFDie::iterator>` (via `make_reverse_iterator` or whatever) and get UB.
