Subject: [PATCH] perf evlist: Add perf_evlist__to_front()

Add a function to move a selected event to the
front of the list.

This is needed because it is not possible
to use the PERF_EVENT_IOC_SET_OUTPUT IOCTL
from an Instruction Tracing event to a
non-Instruction Tracing event.  Thus the
Instruction Tracing event must come first.
