Hi Johannes,
thank you very much for your feedback.

I would like to explain my idea why I add this function to OMPIRBuilder:

Current situation:
1) MLIR does not support LLVM IR function attributes for production quality code. MLIR function passthrough attributes should be used only for PoC work ( https://mlir.llvm.org/docs/Dialects/LLVM/#attribute-pass-through )
2) OpenMP MLIR operations can be translated into multiple LLVM IR functions.

My idea was to add functionality of inserting function attributes after the end of OpenMP MLIR code translation. OMPIRBuilder has necessary knowledge about generated LLVM IR. That's why I decided to do it here and to focus mainly on the code generated for OpenMP pragmas.
