Add field 'ipc' to display instructions-per-cycle.
Example:
perf record -e intel_pt/cyc/u ls
perf script --insn-trace --xed -F+ipc,-dso,-cpu,-tid

Note, the IPC values are low due to page faults at the beginning of
execution. The additional cycles are due to the time to enter the
kernel, not the actual kernel page fault handler.
