So maybe something like the current patch? Then on Fuchsia we could (1) have a
custom implementation of `InitStackAndTls`, (2) wrap the call to
`Thread::InitStackRingBuffer` in `Thread::Init` with a `#if SANITIZER_FUCHSIA`
so it's not called before thread creation, then (2) call
`Thread::InitStackRingBuffer` in the `__sanitizer_thread_start_hook` hook.
