The above reproducer comes from the following:
https://github.com/llvm/llvm-project/blob/main/mlir/test/Dialect/LLVMIR/module-roundtrip.mlir
I observed the following assertion failure with the above reproducer:
```txt
mlir-translate: /path_to_project/llvm-project/llvm/lib/IR/Metadata.cpp:503: static llvm::ValueAsMetadata *llvm::ValueAsMetadata::get(llvm::Value *): Assertion `V && "Unexpected null Value"' failed.
```
