Update.
* sysdeps/i386/tls.h (THREAD_GETMEM_NC): Change interface. It now takes the array member name and the index as parameters. (THREAD_SETMEM_NC): Likewise. * pthread_getspecific.c: Use new THREAD_GETMEM_NC interface. * pthread_setspecific.c: Use new THREAD_GETMEM_NC and THREAD_SETMEM_NC interfaces. * sysdeps/i386/tls.h (THREAD_SETMEM): Use size of member element to decide which code to use. (THREAD_SETMEM_NC): Likewise.

* allocatestack.c (queue_stack): Don't remove stack from list here.
Do it in the caller. Correct condition to prematurely terminate
loop to free stacks.
