    * 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.
