Adding dwarf unwind test, that setups live machine data over the perf test thread and does the remote unwind. At this moment this test fails due to bug in the max_stack processing in unwind__get_entries function. This is fixed in following patch. Need to use -fno-optimize-sibling-calls for test compilation, otherwise 'krava_*' function calls are optimized into jumps and ommited from the stack unwind. So far it's enabled only for x86.
