        description: When fence.i is executed, then any prefetched instructions shall
          be flushed; meaning that pipeline stages are flushed, prefetcher is flushed,
          write buffer is flushed, and data_req_o is eventually supressed.

        comments: TODO missing assert. (Have not checked/covered that the pipeline/writebuffer
          content is actually purged. Or that any memory change WILL be the next instr
          word.)!
