[PATCH] D49234: [DebugInfo] Refactor DWARFDie::iterator to prevent UB

Oh, bother. I tried adding an llvm::reverse call over DWARFDie.children() and it still compiled, even though I made DWARFDie::iterator an input_iterator - so I guess std::reverse_iterator isn't checkingf the trait? :/  That's unfortunate.
