    Allow pretty-printing with partial availability
    
    Especially with local structs, DWARF may only have parts of a variable
    available at runtime.  This change lets us print '?' for inaccessible
    parts, so we can still print the parts we do have.
    
    * tapsets.cxx (dwarf_pretty_print::push_deref): New, try a deref and
      push a '?' instead if it fails.
      (dwarf_pretty_print::recurse): Use push_deref instead of deref.
      (dwarf_pretty_print::recurse_base): Ditto.
      (dwarf_pretty_print::recurse_pointer): Ditto.
      (dwarf_pretty_print::print_chars): Ditto.
