perf tests: Add dwarf unwind test on ARM
...
Adding dwarf unwind test, that setups live machine data over
the perf test thread and does the remote unwind.
Need to use -fno-optimize-sibling-calls for test compilation,
otherwise 'krava_*' function calls are optimized into jumps
and omitted from the stack unwind.
So far it was enabled only for x86.
