        * gcse.c: More comments, whitespace and similar fixes.
        (dump_cuid_table, maybe_set_rd_gen, dump_cprop_data): Delete.
        (dump_pre_data, compute_cprop_local_properties): Likewise.
        (one_classic_gcse_pass): Lose unused argument.  All callers changed.

        All callers changed.  Only alter jumps if ALTER_JUMPS is nonzero.
        Lose unused argument.
        (gcse_main): Always run a cprop pass after finishing global cse.
        (compute_local_properties): New function.
        (hash_scan_pat, hash_scan_insn): No longer call maybe_set_rd_gen.
