These variables are currently unused from what I can see.

For the use_device_ptr/addr clauses for the target data directive. These were used to create block_arguments for these variables, because we wanted to replace all of their uses with new values generated by OMPIRBuilder.

If we are looking for a similar behaviour here then, and we want to add them as block_arguments as well. Then probably this change would be easier once #67164 is merged as that would already have the base code for doing this.
