Subject: [PATCH 6/9] perf/x86/intel: Export new TopDown metrics events for Icelake

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

Export new TopDown metrics 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.
