assign_by_spills call.
(find_reload_regno_insns, lra_split_hard_reg_for): New functions.
* lra-constraints.c (split_reg): Add a new arg. Use it instead of
usage_insns if it is not NULL.
(spill_hard_reg_in_range): New function.
(split_if_necessary, inherit_in_ebb): Pass a new arg to split_reg.
* lra-int.h (spill_hard_reg_in_range, lra_split_hard_reg_for): New
function prototypes.
(lra_assign): Change prototype.
* lra.c (lra): Add code to deal with fails by splitting hard reg
live ranges.
