Subject: [PATCH 05/11] perf, tools, stat: Scale values by unit before metrics

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

Scale values by unit before passing them to the metrics printing functions.
This is needed for TopDown, because it needs to scale the slots correctly
by pipeline width / SMTness.

For existing metrics it shouldn't make any difference, as those generally
use events that don't have any units.
