Log Message

• • • • symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
        defines for the blocks of a blockvector that contain global and
        file-static symbols and the first of the smaller scope contours.
        
      • symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
        decode_line_1, make_symbol_completion_list): Use the above.
        

• • • • symtab.c (list_symbols): Process the first symbol of the
        static psymbols list.
        (types_info): Restore this function from its untimely #if 0.
        It's not perfect, but it is better than nothing.
        (_initialize_symtab): Restore "info types".
