* lra-constraints.c (need_for_split_p): Use more 3 reloads as
threshold for pseudo splitting.
(update_ebb_live_info): Process call argument hard registers and
hard registers from insn definition too.
(max_small_class_regs_num): New constant.
(inherit_in_ebb): Update live hard regs through EBBs. Update
reloads_num only for small register classes. Don't split for
outputs of jumps.
