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

[Philippe Daouadi via llvm-commits]

blastrock added a comment.

Because then I will not be able to write something like

  __sanitizer_enter();
  ThrowAndCatch();
  swapcontext();

because __sanitizer_enter() will be called directly inside swapcontext().
