Gabe Black a13e3debed misc: Stop excluding code when building the NULL ISA.
The BaseCPU needs a little extra hacking because it tries to create
default objects based on what the ISA is. If the ISA isn't recognized,
then the types will be set to None, and some extra checks have been
added as the type is set up.
