[PATCH] D20913: [asan] add primitives that allow coroutine implementations

[Philippe Daouadi via llvm-commits]

I added support for switching from one fiber to another and added that to the unit test. I also added a few ThrowAndCatch calls there to try to trigger the warning that this patch fixes in __asan_handle_no_return.

Btw, if I add the interceptors for swapcontext, then I won't be able to insert these ThrowAndCatch calls in this test. To keep it, do you think I should call swapcontext from a dlopen/dlsym to avoid calling the interceptor? Or do you have another idea?
