Warning fixes:
        * reload1.c (ELIMINABLE_REGS, NUM_ELIMINABLE_REGS): Introduce an
        intermediate structure which has exactly the members provided by
        ELIMINABLE_REGS.  Define NUM_ELIMINABLE_REGS in terms of the
        static intermediate structure.
        (init_elim_table): Xmalloc() `reg_eliminate', and initialize it
        from the intermediate structure.  Do the same analogous fix in
        the case where ELIMINABLE_REGS is not defined.
