always define HAVE_lo_sum
gcc/ChangeLog:
2015-05-23 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
* combine.c (find_split_point): Check the value of HAVE_lo_sum
instead of if it is defined.
(combine_simplify_rtx): Likewise.
* lra-constraints.c (process_address_1): Likewise.
* config/darwin.c: Adjust.
* genconfig.c (main): Always define HAVE_lo_sum.
