H A Dhelper.hdiff 73946f0d556453da9605ee0e258220dfc3dfd622 Thu Mar 07 06:15:26 CST 2019 David Hildenbrand <david@redhat.com> s390x/tcg: Implement VECTOR PACK *

This is a big one. Luckily we only have a limited set of such nasty
instructions.

We'll implement all variants with helpers, except when sources and
the destination don't overlap for VECTOR PACK. Provide different helpers
when the cc is to be modified. We'll return the cc then via env->cc_op.
