fix futures creating aliasing mutable and shared ref Fixes the problem described in https://github.com/solson/miri/issues/532#issuecomment-442552764: `set_task_waker` takes a shared reference and puts a copy into the TLS (in a `NonNull`), but `get_task_waker` gets it back out as a mutable reference. That violates "mutable references must not alias anything"!
