perf tools: Move tile barrier.h stuff to tools/arch/tile/include/asm/barrier.h

Browse source 
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
* CONFIG_ needed for properly doing that.
