I think we need to organize and test this patch a bit better.

1. Is the following sentence in the summary still correct or is the code from LLVM AtomicExpand?
```
We first refactor relevant functionality from Clang Codegen to LLVM Frontend, and then interface the OpenMPIRBuilder with the same. 
```
2. The test removed from Todo is an atomic read, why was it not added back?
3. The code change in OpenMPToLLVMIRTranslation.cpp is the Capture Code generation. There is no test for this. Also cand this change be shared with the Update code generation?
4. We need tests in the OpenMP IRBuilder and in MLIR for the changes.
