Subject: [PATCH 1/9] perf, tools, stat: Move sw clock metrics printout to stat-shadow

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

The sw clock metrics printing was missed in the earlier move to
stat-shadow of all the other metric printouts. Move it too.

Acked-by: Jiri Olsa <jolsa@...nel.org>
v2: Fix metrics printing in this version to make bisect safe.
Signed-off-by: Andi Kleen <ak@...ux.intel.com>
