        * fold-vec-ld-char.c: Add lxv insn to expected output.
        * fold-vec-ld-double.c: Add lxv insn to expected output.
        * fold-vec-ld-float.c: Add lxv insn to expected output.
        * fold-vec-ld-int.c: Add lxv insn to expected output.
        * fold-vec-ld-longlong.c: Add lxv insn to expected output.
        * fold-vec-ld-short.c: Add lxv insn to expected output.
