Constify 'la_name' in struct language_defn

Hi,
When I add another name of language, I find field 'la_name' can be
'const char *'.  This patch is to constify it.

gdb:

2013-11-07  Yao Qi  <yao@codesourcery.com>

	* language.c (language_str): Return const char *.
	(add_language): Add const to 'language_names'
	* language.h (struct language_defn) <la_name>: Add const.
	(language_str: Update declaration.
