This revision now requires changes to proceed.

As far as I can tell, this is just a matter of missing transforms for usub_sat. I've applied https://github.com/llvm/llvm-project/commit/6261adfa51f2d93c8258e7b2d9811d607f3e50a5 and https://github.com/llvm/llvm-project/commit/3f53a58597bc84418f8b83934ef2f5c5d615626b to fix the issue from your example. Let me know if you see further issues.
