target/s390x: implement mvcos instruction
This adds support for the MOVE WITH OPTIONAL SPECIFICATIONS (MVCOS) instruction. Allow to enable it for the qemu cpu model using qemu-system-s390x ... -cpu qemu,mvcos=on ... This allows to boot linux kernel that uses it for uacccess. We are missing (as for most other part) low address protection checks, PSW key / storage key checks and support for AR-mode. We fake an ADDRESSING exception when called from problem state (which seems to rely on PSW key checks to be in place) and if AR-mode is used. user mode will always see a PRIVILEDGED exception. This patch is based on an original patch by Miroslav Benes (thanks!).
