[PATCH] Recognize new DWARF5/GCC5 DW_LANG Fortran 2003 and Fortran 2008 standards.

[Mark Wielaard]

DWARFv5 defines and GCC5 may output two new DW_LANG constants for the
Fortran 2003 and Fortran 2008 standards. Recognize both as variants of
language_fortran.

gdb/ChangeLog:

	* dwarf2read.c (set_cu_language): Recognize DW_LANG_Fortran03 and
	DW_LANG_Fortran08 as language_fortran.

include/ChangeLog

	* dwarf2.h: Add DW_LANG_Fortran03 and DW_LANG_Fortran08.

The dwarf2.h from gcc already contains the same constant definitions.
