* toplev.c (backend_init_target): Call initializer for lower-subreg
pass.
* lower-subreg.c (LOG_COSTS, FORCE_LOWERING): New macros.
(default_target_lower_subreg): New variable.
(this_target_lower_subreg): Likewise.
(twice_word_mode, choices): New macros.
(shift_cost, compute_splitting_shift, compute_costs)
