case the assumption is that vector elements are required appear to be
executed in sequential Program Order, element 0 being the first.
-* LD/ST ffirst treats the first LD/ST in a vector (element 0) as an
- ordinary one. Exceptions occur "as normal". However for elements 1
- and above, if an exception would occur, then VL is **truncated** to the
- previous element.

* Data-driven (CR-driven) fail-on-first activates when Rc=1 or other
CR-creating operation produces a result (including cmp). Similar to
branch, an analysis of the CR is performed and if the test fails, the
