[qemu-s390x] [PATCH 0/7] Some improvements in z/Arch instructions support

[Pavel Zbitskiy]

Found while attempting to run an old tool in qemu.

* BAL and BALR:    Added.
* CSST:            Qemu crashed after an accidental jump to garbage.
* IPM:             A tool produced an incorrect output.
* EX TRT/TRTR:     A tool ran quite slow.
* PACK:            A tool produced an incorrect output.
* CVB, CVBY, CVBG: Added.

Changes since v1:
* Tests.
* Call pc_to_link_info() instead of op_bas().
* Clarified CSST commit message.
* Rewrote IPM using extract/deposit.
* Clarified PACK commit message.
* Do not use LowCore for CONFIG_USER_ONLY.
* Reduce duplication in CVB code.
