14e8ee4385 ia64: If ATOMIC_OPS_H is defined, use a simple flag rather than a 
pthread_mutex lock to mediate access to the script-cache.
	This has the advantage of avoiding the relatively expensive
	sigprocmask()/pthread_mutex_lock()/pthread_mutex_unlock()/sigprocmask()
	sequence when caching is enabled.  Also, with thread-local caching,
	libunwind should scale perfectly to large number of CPUs/threads.

e433ec3820 (unw_create_addr_space): Drop call to ia64_script_cache_init(). It's 
not needed because we default to "no caching" and if the application
	turns on caching via unw_set_caching_policy(), the cache will get
	initialized at that time.

629d7d3263 (ia64_per_thread_cache): Initialize busy/lock member. 
(get_script_cache): Return NULL if caching is disabled.  If
	HAVE_ATOMIC_OPS_H is defined, set the busy flag and if
	the script cache is busy already, return NULL.
(put_script_cache): Don't allow it to be called for UNW_CACHE_NONE case.
	If HAVE_ATOMIC_OPS_H is defined, clear the "busy" flag via
	AO_CLEAR.
(ia64_get_cached_proc_info): If we're unable to acquire the cache,
	return -UNW_ENOINFO.
(script_init): New function.
(script_new): Replace open code with call to script_init().
(uncached_find_save_locs): New function.
(ia64_find_save_locs): Move code for uncached case to
	uncached_find_save_locs().  If get_script_cache() is unable to
	lock the script-cache, fall back to uncached_find_save_locs().
(ia64_script_cache_init): Delete.
