* lra-int.h (struct lra_reg): Add field actual_call_used_reg_set.
* lra.c (initialize_lra_reg_info_element): Add init of
actual_call_used_reg_set field.
(lra): Call lra_create_live_ranges before lra_inheritance for
-fuse-caller-save.
* lra-assigns.c (lra_assign): Allow call_used_regs to cross calls for
-fuse-caller-save.
* lra-constraints.c (need_for_call_save_p): Use actual_call_used_reg_set
instead of call_used_reg_set for -fuse-caller-save.
* lra-lives.c (process_bb_lives): Calculate actual_call_used_reg_set.
