can be seen that the offset of 0-7 would be sufficient. Unfortunately
however some operations are EXTRA2-encoded it is **not possible**
to increase the GPR/FPR register number by one, because EXTRA2-encoding

*Hardware Implementor's note: with the offsets only being immediates
and with register numbering being entirely immediate as well it is
