Adrian Hunter 797efbc523 perf tools: Add guest_cpu to hypervisor threads ...

It is possible to know which guest machine was running at a point in time
based on the PID of the currently running host thread. That is, perf
identifies guest machines by the PID of the hypervisor.

To determine the guest CPU, put it on the hypervisor (QEMU) thread for
that VCPU.

This is done when processing the id_index which provides the necessary
information.
