perf/x86: Add 'index' param to get_event_constraint() callback
This patch adds an index parameter to the get_event_constraint() x86_pmu callback. It is expected to represent the index of the event in the cpuc->event_list[] array. When the callback is used for fake_cpuc (evnet validation), then the index must be -1. The motivation for passing the index is to use it to index into another cpuc array.
