This patch adds the CPU model definitions that are known on s390x -
like z900, zBC12 or z13. For each definition, introduce two CPU models:
1. Base model (e.g. z13-base): Minimum feature set we expect to be around
on all z13 systems. These models are migration-safe and will never
change.
2. Flexible models (e.g. z13): Models that can change between QEMU versions
and will be extended over time as we implement further features that
are already part of such a model in real hardware of certain
configurations.
We want to work on features using ordinary bitmap operations, however we
can't initialize a bitmap statically (unsigned long[] ...). Therefore we
store the generated feature lists in separate arrays and convert them to
proper bitmaps before registering all our CPU model classes.
