Dmitry Vyukov b3587836bc [ASAN] Pass previous stack information through __sanitizer_finish_switch_fiber 
This patch extends __sanitizer_finish_switch_fiber method to optionally return previous stack base and size.

This solves the problem of coroutines/fibers library not knowing the original stack context from which the library is used. It's incorrect to assume that such context is always the default stack of current thread (e.g. one such library may be used from a fiber/coroutine created by another library). Bulding a separate stack tracking mechanism would not only duplicate AsanThread, but also require each coroutines/fibers library to integrate with it.
