These invalid lifetime intrinsics were created by Autoupgrade due to a bug that was fixed with https://github.com/llvm/llvm-project/pull/204601

One idea that @jayfoad had suggested is to cleanup unused intrinsics in the bitcode reader. Other is to specifically handle these two. @cofibrant how can I get the bitcode file that's failing to test any fix? Additionally, what's the urgency of fixing this?
