Subject: [PATCH 06/21] perf tools: Add arbitary aliases and support names with -

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

- Add missing scanner symbol for arbitrary aliases inside the config
  region.

- looks nicer than _, so allow - in the event names. Used for various of
  the arch perfmon and Haswell events.
