Avi Kivity 8d6e575f59 perf_fast_forward: report instructions per fragment 
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
