Temporarily revert symbol lookup cache.
clear_symtab_users calls breakpoint_re_set before
observer_notify_new_objfile(NULL), and thus symbol lookup
done during breakpoint_re_set will see a stale cache.
Presumably we just need to move the call to observer_notify_new_objfile(NULL)
to before breakpoint_re_set, but need to check for other such issues,
and 7.9 is scheduled to branch tomorrow.
