Similar to:
https://github.com/RKSimon/llvm-project/blob/20aff2085c358d3e112b245494161ddb9ffe0410/llvm/lib/Analysis/ValueTracking.cpp#L2827-L2829
The actual change is trivial but this will require test coverage as well - these might be possible by extending existing DAG tests, else maybe add unit tests like we did in https://github.com/llvm/llvm-project/pull/181485
