The change looks good to me, but can you please adjust the test coverage so the second condition is not implied (i.e. folds to true) by the first? In that case the transform isn't really meaningful.

As you mark https://github.com/llvm/llvm-project/issues/69928 as fixed, you should also add the test case from there.
