After updating to current sources today, I have noticed a regression in 
print-threads.exp which is due to some missing logic in my June 4th patch.  The 
problem is a timing issue (it does not occur for my June 4th build).  There is a 
gdb_assert in thread_from_lwp() which gets triggered because the th_valid flag 
has not been set for a zombie thread's thread_info struct.

This patch fills in the zombie thread's thread_info private area since the 
information is indeed valid and available.

Ok to commit?

         * thread-db.c (thread_get_info_callback): Fill in the thread_info
         struct if one exists, even if we are dealing with a zombie thread.
