Right, gdb is not performance critical. gdb is the reason for moving it 
out of the union, performance is the reason for having it in kvm_run at all.
There's only more reason to it: with a little tweaking in kuli, we'll be 
able to get rid of KVM_S390_SET_INITIAL_PSW ioctl with this change. That 
removes one oddity that makes us different from other platforms.
