- The actual reason I started this: minor lowering updates in the golden LLVM IR - Process.inc changed enough to need a patch context update. - https://github.com/llvm/llvm-project/pull/123126 added `proto_library` uses without a `load`, which is broken in bazel 8 - Just commenting these out because we don't use them. I'll follow up separately about a possible fix, but continuing to use `WORKSPACE` is a bigger issue LLVM probably should address. - Note this update is also triggering removal of `migrate_cpp`, in #4887
