OK for trunk?

        (df_remove_problem): Make local "problem" be const.
        * df-problems.c (problem_RD): Make const.
        (problem_LR): Likewise.
        (problem_LIVE): Likewise.
        (problem_MIR): Likewise.
        (problem_CHAIN): Likewise.
        (problem_WORD_LR): Likewise.
        (problem_NOTE): Likewise.
        (problem_MD): Likewise.
        * df-scan.c (problem_SCAN): Likewise.
        * df.h (struct df_problem): Make field "dependent_problem" be
        const.
        (struct dataflow): Likewise for field "problem".
