H A Dhelper.hdiff 697a45d6952a897ea300f8071a162cbb464fade0 Thu Apr 11 04:54:53 CDT 2019 David Hildenbrand <david@redhat.com> s390x/tcg: Implement VECTOR GALOIS FIELD MULTIPLY SUM (AND ACCUMULATE)

A galois field multiplication in field 2 is like binary multiplication,
however instead of doing ordinary binary additions, xor's are performed.
So no carries are considered.

Implement all variants via helpers. s390_vec_sar() and s390_vec_shr()
will be reused later on.
