Use a hardware counter to report instructions per fragment. Results vary from ~4k insns/f when reading sequentially to more than 1M insns/f. Instructions per fragment can be a more stable metric than frags/sec. It would probably be even more stable with a fake file implementation that works in-memory to eliminate seastar polling instruction variation. Closes #8660
