    * dwarfgen.cc: Add create_debug_sup_content() so we
      could create a .debug_sup print testcase.
      New option --add-debug-sup. and cmdoptions.adddebugsup
      flag.
    * general.h: Added  bool adddebugsup.
    * ireptodbg.cc: Ugly indent error fixed.

    * irepattrtodbg.cc: DWARF5 required adding new
      DW_FORM_CLASS entries in libdwarf.h.
      To aviod annoying warnings from dwarfgen we now
      add the new ones. We do not do anything with them
      at present.
