notify ASAN about M:N threading stack switches
In a similar way to how we do it with fibers in cont.c, we need to call
__sanitize_start_switch_fiber and __sanitize_finish_switch_fiber around
the call to coroutine_transfer to let ASAN save & restore the fake stack
pointer.
When a M:N thread is exiting, we pass `to_dead` to the new
coroutine_transfer0 function, so that we can pass NULL for saving the
stack pointer. This signals to ASAN that the fake stack can be freed
(otherwise it would be leaked)
