perf annotate: Finally display IPC and cycle accounting

Add two new columns to the annotate display and display the average
cycles and the compute IPC if available.

When the LBR was not in any branch mode the IPC computation is
automatically disabled. We still display the cycle information.

Example output (with made up numbers):

The second column is the IPC and third average cycles.
