s390x/tcg: CCW hotplug, facilities, instructions

Both series in one piece as (most probably) most reviewing is done.

Wire up some io instructions and implement new facilitites. Make sure to take care of MTTCG when it comes to atomic operations. Make CCW hotplug work.

As we are now able to install/boot a Fedora 26/27 as well as an upstream kernel compiled for z12, let's bump up the QEMU cpu model to a very stripped down version of a z12 (with missing base features). Take care of backwards compatibility (as we defined the QEMU model as migration-safe).

v2 -> v3:
- squashed the ASI/ASGI and ALSI/ALSGI patches.
- Both now emulate old behavior.
- "s390x/tcg: implement Interlocked-Access Facility 2"
- now also emulates old behavior.
- "s390x/tcg: implement SET CLOCK PROGRAMMABLE FIELD"
- now forwards r1 into the helper.
- "s390x/tcg: implement extract-CPU-time facility"
- takes care of user-only
- "s390x: change the QEMU cpu model to a stripped down z12"
- const -> static const for two feature bitmaps
