S/390: Implement vcond expander for V1TI,V1TF
Currently gcc does not emit wf{c,k}* instructions when comparing long
double values. Middle-end actually adds them in the first place, but
then veclower pass replaces them with floating point register pair
operations, because the corresponding expander is missing.

* config/s390/vector.md (V_HW): Add V1TI in order to make
vcond$a$b generate vcondv1tiv1tf.
