da6d856751 tools include: Add basic atomic.h implementation from the kernel sources 
Uses the arch/x86/ kernel code for x86_64/i386, fallbacking to a gcc
intrinsics implementation that has been tested in at least sparc64.

Will be used for reference counting in tools/perf.

25cd480e44 tools: Remove bitops/hweight usage of bits in tools/perf 
We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...
