New vms that read cog images - as in cog is no longer a one-way street? That would make it safer/easier to test.

Thanks, StackToRegisterMappingCogit is really impressive. IIRC for the
4.1.1 VM Andreas fixed something about ImageSegment loading which is
missing from the CogVMs. It would be good to have that fix, because now
arrayOfRoots is nil when I'm trying to load an ImageSegment. It's not
urgent at all, because I could work the problem around using the new
SqueakVMs which can read Cog images and have the fix.
