(__pthread_initialize_manager): Determine __pthread_initialize_manager
value.

* linuxthreads/sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add
load of spin lock to prime the cache before the atomic compare and
exchange operation (cmpxchg4). This avoids the spinning on the
cmpxchg4 instruction and reduces movement of the cache line back

from Intel). This basically makes the implementation operate the
same as the Linux kernel implementation.

Bugfixes to the variant of the code for machines with no compare
and swap.

node was not being properly enqueued, due to failing to update
the lock->__status field.

being set inappropriately, causing the suspend function to be called
with a null self pointer and crash.

A few optimizations. Got rid of unnecessary wakeups of timer threads,
tightened up some critical regions and micro-optimized some list
manipulation code.
* sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
Returns int value now to indicate whether timer was queued at head.

new return value from __timer_thread_queue_timer to avoid waking
