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.
