The problem with that is:
- `OpenMPIRBuilder::Ident` are created and maintained by the functions of the `OpenMPIRBuilder`. So I think it would be preferable to keep the knowledge of these structs within the builder.
- The `CodeExtractor` is not OpenMP-related and I think it would better not to leak any non-related OpenMP-details to it.

Of course it is better not to add something and then remove it. But I think it logically isolates things better this way.
