Originally, S390 also shared this code as it too has to insert watchpoints on 
all threads.  However, it stores its own list of watchpoints so it doesn't 
require breakpoint.c to go through the breakpoint list and find them anymore.

I had thought of making the function ia64-only after simplifying S390 but I 
figured there would be in all likelihood more platforms in the future that would 
need it.

Either way is fine with me.
