Summary so far:
* failfirst needs to be an illegal exception if all-scalar
* non-zeroing predication on all-scalar with VL>1 requires
all relevant bits to be set, this changes to the **first**
- bit for auto-VL=1
+ bit for auto-VL=1. requires an extra reduction instruction.
+* sv.branches should not be touched. at all.
