No, because "env" location and size are specific to S390CPU.

And yes, it is ugly boilerplate code, but it cannot be solved with my
CPU_COMMON field movements alone (which partially add explicit reset
code based on the field location), there's quite a large number of
per-target fields that get reset that way, some intentionally, some
accidentally. ;-)
