Fields:
SNZ=1 a value "1" is put in place of "0".
* **inv CR-bit** just as in branches (BO) these bits allow testing of
a CR bit and whether it is set (inv=0) or unset (inv=1)
-* **RG** inverts the Vector Loop order (VL-1 downto 0) rather
- than the normal 0..VL-1
+* **RG** Reverse-Gear: inverts the Vector Loop order (VL-1 downto 0) rather
+ than the normal 0 upto VL-1
* **SVM** sets "subvector" reduce mode
* **VLi** VL inclusive: in fail-first mode, the truncation of
VL *includes* the current element at the failure point rather
