Summary: The patch https://github.com/llvm/llvm-project/pull/80847 introduced some changes to how we build tablegen. Some files weren't build included properly on my build. We don't need to fish out the objects directly from an object library build, we can simply add it to the link libraries and CMake will include them for you. This fixed the issue of missings defs for me and is more canonical.
