* lra-int.h (struct lra_operand_data, struct lra_insn_reg): Add
member early_clobber_alts.
* lra-lives.c (reg_early_clobber_p): New.
(process_bb_lives): Use it.
* lra.c (new_insn_reg): New arg early_clobber_alts. Use it.
(debug_operand_data): Initialize early_clobber_alts.
(setup_operand_alternative): Set up early_clobber_alts.
(collect_non_operand_hard_regs): Ditto. Pass early clobber
alternatives to new_insn_reg.
(add_regs_to_insn_regno_info): Add arg early_clobber_alts. Use
it.
(lra_update_insn_regno_info): Pass the new arg.
