(BF, BFA etc) are only 3-bits.
With SVP64 extending the number of CR *Fields* to 128, the number of
-CR *Registers* extends to 16, in order to hold all 128 CR *Fields*
+32-bit CR *Registers* extends to 16, in order to hold all 128 CR *Fields*
(8 per CR Register). Then, it gets even more strange, when it comes
to Vectorisation, which applies to the CR *Field* numbers. The
hardware-for-loop for Rc=1 for example starts at CR0 for element 0,
