Update.
* pthreadP.h: Mark declarations of __find_in_stack_list, __free_tcb, and __deallocate_stack with internal_function. * pthread_create.c: Adjust definitions appropriately. * allocatestack.c: Likewise. * pthread_join.c: Add one more __builtin_expect. * pthread_timedjoin.c: Likewise. * pthread_getspecific.c (__pthread_getspecific): Clear data->data not data of sequence number does not match. Add one __builtin_expect.
