c++: fix cxx_print_type's template-info dumping

c++: fix cxx_print_type's template-info dumping

Unlike DECL_TEMPLATE_INFO which is stored in DECL_LANG_SPECIFIC,
TYPE_TEMPLATE_INFO isn't stored in TYPE_LANG_SPECIFIC, so we don't
need to check for both in cxx_print_type.  This fixes dumping the
template-info of ENUMERAL_TYPE and BOUND_TEMPLATE_TEMPLATE_PARM,
which seem to never have TYPE_LANG_SPECIFIC.

gcc/cp/ChangeLog:

	* ptree.cc (cxx_print_type): Remove TYPE_LANG_SPECIFIC
	test guarding TYPE_TEMPLATE_INFO.
