Hi,

Randomized testing found a number of issues in the s390x emulation.
This series fixes 6 of them (patches 2-7) and adds tests (patches
8-12); patch 1 is a cosmetic improvement needed for the EPSW test.

There are more issues, but I thought it would be better to send this
batch now.

Best regards,
Ilya
