Subject: [PATCH V2 17/23] perf/x86/intel: Export new top down events for Icelake

From: Andi Kleen <ak@...ux.intel.com>

Export new top down events for perf that map to the sub metrics
in the metrics register, and another for the new slots fixed counter.
This makes the new fixed counters in Icelake visible to the perf
user tools.
