I wonder if we could make the operation `ConstantLike` and add it to https://github.com/llvm/llvm-project/blob/4c1bc59365360f7f24a5c82b8cebd2b52634879a/mlir/lib/Dialect/LLVMIR/IR/LLVMDialect.cpp#L4687 so that metadata attribute are materialized as such metadata as value operations. That way the metadata node would all be moved to the entry block.
