This should be refactored into `OpenMPIRBuilder::createInReduction` or similar, if this isn't too dissimilar from the handling of `in_reduction` in other constructs. If it's too much effort to get all those cases to share the same logic, as a first step it should at least be moved it to an `OpenMPIRBuilder::createTargetInReduction` function.
