[lib] Optimise thread_call by caching pointer to thread history in the thread
2006-07-25 Paul Jakma <paul.jakma@sun.com>
* thread.h: (struct thread) Add a cache pointer to the struct
cpu_thread_history, if it is known - saving hash lookup on
each thread_call.
* thread.c: (thread_call) Cache the pointer to the
cpu_thread_history, so that future thread_calls of same
thread can avoid the hash_lookup.
