Dmitry Vyukov 47b7c5c912 [asan] add primitives that allow coroutine implementations 
This patch adds the __sanitizer_start_switch_fiber and
__sanitizer_finish_switch_fiber methods inspired from what can be found here
2ea64dd249 .

These methods are needed when the compiled software needs to implement
coroutines, fibers or the like. Without a way to annotate them, when the program
jumps to a stack that is not the thread stack, __asan_handle_no_return shows a
warning about that, and the fake stack mechanism may free fake frames that are
still in use.
