-   Unfortunatly, thanks to some legacy architectures, this doesn't

-   (see MIPS).  Such architectures should be using different register
-   numbers for the different sized views of identical registers.
-
-   Anyway, the up-shot is that, until that mess is fixed, core code
-   can end up being very confused - should the RAW or VIRTUAL size be
-   used?  As a rule of thumb, use REGISTER_VIRTUAL_SIZE in cooked
-   code, but with the comment:
