<pre>
    When building MLIR project with option -DLLVM_USE_SANITIZER="Address;Undefined",  we face the following error.



```$ build/bin//mlir-opt --help
~/llvm-project-public/llvm/include/llvm/Support/CommandLine.h:588:13: runtime error: load of value 1, which is not a valid value for type 'const (anonymous namespace)::TestOptionsPass::Enum'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ~/llvm-project-public/llvm/include/llvm/Support/CommandLine.h:588:13 in 
```
The error goes away if we compile without sanitizers.

The first commit to introduce this issue is 710b5a12324e54d42632985c46a3071fc2504fc9 (@chsigg )

The cmake command with sanitizer is :
```
cmake -G Ninja ../llvm -DLLVM_ENABLE_PROJECTS=mlir    -DLLVM_BUILD_EXAMPLES=ON -DLLVM_TARGETS_TO_BUILD="host"    -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_ASSERTIONS=ON    -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_ENABLE_LLD=ON    -DLLVM_CCACHE_BUILD=ON -DLLVM_USE_SANITIZER="Address;Undefined" -DMLIR_INCLUDE_INTEGRATION_TESTS=ON 
```
