(unw_local_addr_space): Initialize statically, so it's valid right away.
(put_unwind_info): New function. (get_dyn_info_list_addr): Ditto. (ia64_init): Initialize big_endian member in local_addr_space and put_unwind_info and get_dyn_info_list_addr callbacks in the accessor's structure. }(Logical change 1.30)
