e4114cb89e [PATCH] Sync libiberty/ & include/ with GCC - addendum: update elfcpp/dwarf.h with the new DW_CFA_DUP macro. 
From the original email:
  Note this brings in the interface files for libcc1/G++ as well, which
  we will be needing in GDB soon anyway.  That commit renamed a method
  in the C interface and that required a small update to GDB's compile/
  code, which I've included that in this patch to keep the tree
  building.

From the follow up email:
  That breaks gold:

2d9afefe22 [gold] Recognize DWARF5/GCC5 DW_LANG_Fortran03 and DW_LANG_Fortran08. 
DWARFv5 defines and GCC5 may output two new DW_LANG constants for the
Fortran 2003 and Fortran 2008 standards. Recognize both in gold gdb-index
as unsupported.

For consistency also add the other new DWARF5/GCC5 language constants in
the elfcpp::DW_LANG enum to match include/dwarf2.h.

elfcpp/ChangeLog:

	* dwarf.h (enum DW_LANG): Add DW_LANG_C_plus_plus_11,
	DW_LANG_C11, DW_LANG_C_plus_plus_14, DW_LANG_Fortran03 and
	DW_LANG_Fortran08 from ../include/dwarf2.h.

gold/ChangeLog:

	* gdb-index.cc (Gdb_index_info_reader::visit_top_die): Recognize
	DW_LANG_Fortran03 and DW_LANG_Fortran08.
