> What about a new header file in `mlir/include/mlir/Target/LLVMIR/Dialect/**` shared by `mlir/lib/Target/LLVMIR/Dialect/OpenACC/OpenACCToLLVMIRTranslation.cpp` and `mlir/lib/Target/LLVMIR/Dialect/OpenMP/OpenMPToLLVMIRTranslation.cpp`. That should be doable. 
`mlir/lib/Target/LLVMIR/Dialect/OpenACC/OpenACCToLLVMIRTranslation.cpp` and `mlir/lib/Target/LLVMIR/Dialect/OpenMP/OpenMPToLLVMIRTranslation.cpp` already have access to the common `mlir::Location` type.

Problem is that `OMPIRBuilder.cpp` is the only common file between them  where I can move the two functions to. Currently there are no `mlir/**` include files in `OMPIRBuilder.cpp` and it seems to me like a strict design choice to have it that way.
