<pre>
    hi, I encountered a bug while trying to go from .mlir to .ll.

The command I was using is the following

```
mlir-translate -opaque-pointers=0 \
                        --mlir-to-llvmir \
 output/04baseline.mlir \
                        -o output/05baseline.ll
```

The error I encounter due to a segmentation fault is the following 

```
ElementsAttr does not provide iteration facilities for type `mlir::Attribute`, see attribute: dense_resource<__elided__> : tensor<16x7xf32>
invalid `T` for ElementsAttr::getValues
UNREACHABLE executed at /working_dir/llvm-project/mlir/include/mlir/IR/BuiltinAttributeInterfaces.h:307!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
