I tried to have:

  using section_iterator = filtered_iterator<obj_section *, filter_out_null_bfd_section>;
  using const_section_iterator
    = filtered_iterator<const obj_section *, filter_out_null_bfd_section>;

  /* Return an iterable that yields the "non-null" sections of this objfile.
     That is, the sections for which obj_section::the_bfd_section is
     non-nullptr.  */
  iterator_range<section_iterator> sections ()
  {
    return (iterator_range<section_iterator>
	    (section_iterator (sections_start, sections_end),
	     section_iterator (sections_end, sections_end)));
  }

  iterator_range<const_section_iterator> sections () const
  {
    return (iterator_range<const_section_iterator>
	    (const_section_iterator (sections_start, sections_end),
	     const_section_iterator (sections_end, sections_end)));
  }


But it would require some changes that extend past the scope of this
patch.  Given that this patch doesn't make things worse than they
already are, I'll push my original patch.

Thanks,
