Ian Rogers 1fd09e299b perf metric: Add --metric-no-threshold option ...

Thresholds may need additional events, this can impact things like
sharing groups of events to avoid multiplexing. Add a flag to make the
threshold calculations optional. The threshold will still be computed
if no additional events are necessary.
