perf tests x86: Add dwarf unwind test
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.
