This is the 2nd part of getting x86 threaded watchpoints to work.  It involves 
some fixes to breakpoint.c.

The most major change is that a check has been added for a hardware_watchpoint 
to ensure that the stopped data address matches the watchpoint address.  I do 
not know if there are platforms that have hardware_watchpoints but cannot tell 
what the data address is.  If this problem exists, I can easily add a flag to 
determine if the stopped address can be used or not.  Alternatively, the default 
stopped_data_address for such a platform could return a special value that the 
comparison check could treat as "don't know".

Comments?  Ok?

         * breakpoint.c (print_it_typical): Do not issue a warning message
         if we find a bp_thread_event and there are other items on the
         stop list.
         (bpstat_stop_status): When dealing with a hardware_watchpoint,
         check if the stopped data address matches the watched address
         for the current breakpoint in the list.  When dealing with a
         read or access watchpoint, if the address does not match, remember
         to turn off the print for the newly added bpstat.
