These passes will be replaced soon as we move to the target extension based resource handling in the DirectX backend, but removing them now before the replacement stuff is all up and running would be very disruptive. However, we do need to move these passes out of the way to avoid symbol conflicts with the new DXILResourceAnalysis in the Analysis library. Note: I tried an even simpler hack in #100698 but it doesn't really work. A rename is the most expedient path forward here. Pull Request: https://github.com/llvm/llvm-project/pull/101393
