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.

http://dwarfstd.org/ShowIssue.php?issue=141121.1
The dwarf2.h from gcc already contains the same constant definitions.

OK.

Note that changes approved in gcc's include/ are pre-approved to
be applied on their own in the binutils-gdb.git repository at
the same time they are applied on the GCC side. Otherwise,
there are some period scripts that resync the two copies. But
I'm not sure whether that's well controlled or not and what
the frequency is. I personally usually push to both repositories
at the same time, mostly to avoid potential extra work for someone
else...
