I think I see the problem. `SelectionDAGISelLegacy::getAnalysisUsage` was not added now that the analyses are required - it still has an `#ifnef NDEBUG` around the `AU.addRequired<TargetTransformInfoWrapperPass>()` - I haven't yet found the equivalent code for the new pass manager but I'm sure I will imminently.
