KVM: s390: Add support for machine checks.
Add support for injecting machine checks (only repressible
conditions for now).
This is a bit more involved than I/O interrupts, for these reasons:
- Machine checks come in both floating and cpu varieties.
- We don't have a bit for machine checks enabling, but have to use
a roundabout approach with trapping PSW changing instructions and
watching for opened machine checks.
