[PATCH] Fix up rv1.C with -gdwarf-4 -fno-debug-types-section

[Jakub Jelinek]

Hi!

Whether DW_TAG_rvalue_reference_type or DW_TAG_reference_type
should be emitted for rvalue references shouldn't depend on
whether .debug_types section is emitted or not, it should
depend just on whether emitting DWARF4+ or not.

Ok for trunk?

        * dwarf2out.c (modified_type_die, gen_reference_type_die): Use
        DW_TAG_rvalue_reference_type even for
        -gdwarf-4 -fno-debug-types-section.
