Message:

Make sure that a thread with uninitialized TLS does not need to call malloc()
to initialize it.

For threads and tasks created by loader, we create TLS beforehand and pass
it to the child. For tasks spawned directly by the kernel, we require it is
a static executable and allocate the initial TLS using as_area_create() instead
of the libc allocator.
