    * lra-int.h (LRA_LOSER_COST_FACTOR, LRA_MAX_REJECT): New macros.
    * lra.c (setup_operand_alternative): Use them.
    * lra-constraints.c (LOSER_COST_FACTOR, MAX_OVERALL_COST_BOUND):
    Remove.
    (process_alt_operands): Use LRA_LOSER_COST_FACTOR and
    LRA_MAX_REJECT.  Accumulate reject instead of setting for
    non-const.
    (curr_insn_transform): Initialize best_losers and best_overall by
    INT_MAX.
