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.
