S/390: Add widening vector mult lo/hi patterns
Add support for widening vector multiply lo/hi patterns. These do not
directly match on IBM Z instructions but can be emulated with even/odd
+ vector merge.
gcc/ChangeLog:

* config/s390/vector.md ("vec_widen_umult_lo_<mode>")
("vec_widen_umult_hi_<mode>", "vec_widen_smult_lo_<mode>")
