failure to raise - terminator with potential side effects

Repro: given https://github.com/wsmoses/Enzyme-GPU-Tests/blob/1e999f921f042568b2290b5207b06749ac4b069f/LBM/lbm.cu, call

error message:

```
'llvm.invoke' op transformation does not support terminators with side effects
```

This presumably comes from upstream https://github.com/llvm/llvm-project/blob/b757bc8b13b1088e2f2b1b98aa33ebb16334b59d/mlir/lib/Transforms/Utils/CFGToSCF.cpp#L1247-L1251 and may be just a missing interface impl.

Start with the CUDA reproducer in LBM/lbm.cu and the upstream CFGToSCF.cpp code around lines 1247-1251. Trace how the 'llvm.invoke' transformation handles terminators with side effects and determine whether the reported interface is missing. Done means the provided command no longer emits this transformation error, with the behavior covered or clarified.
