PR10461: Add support for C++ classes and references

* dwarf_wrappers.cxx (dwarf_type_name): Name class and reference types.
* dwflpp.cxx (dwflpp::iterate_over_globals): Capture class names.
  (dwflpp::print_members): Permit classes, and dig into inheritance.
  (dwflpp::find_struct_member): Ditto.
  (dwflpp::translate_components): Handle classes and references.
  (dwflpp::translate_final_fetch_or_store): Ditto.
* loc2c.c (c_translate_pointer): Treat references as simple pointers.
