Subject: [PATCH 20/30] perf tools: Move generic barriers out of perf-sys.h

From: Arnaldo Carvalho de Melo <acme@...hat.com>

We will need it for atomic.h, so move it from the ad-hoc tools/perf/
place to a tools/ subset of the kernel arch/ hierarchy.

The parisc stuff was just using the asm-generic/barrier.h, no need to
introduce a tools/arch/parisc/ tree just yet.
