Summary: Previous patch (r360409) introduced the "symbol file unwind plan" concept, but that plan wasn't used for unwinding yet. With this patch, we start to consider the new plan as a possible strategy for both synchronous and asynchronous unwinding. I also add a test that asserts that unwinding via breakpad STACK CFI info works end-to-end.
