Arnaldo Carvalho de Melo d3bd708114 perf tools: Move tile barrier.h stuff to tools/arch/tile/include/asm/barrier.h
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.

* Probably when we continue work on tools/ Kconfig support to have all the
