are directly equivalent to the strict Program Order Execution of
their element-level operations.
- R0,CA = A0+B0+CA
+ R0,CA = A0+B0+CA adde r0,a0,b0

- R1,CA = A1+B1+CA
+ R1,CA = A1+B1+CA adde r1,a1,b1

- R2,CA = A2+B2+CA
+ R2,CA = A2+B2+CA adde r2,a2,b2
Thus, due to sequential execution of `adde` both consuming and producing
a CA Flag, `sv.adde` is in effect an alias for Vectorised add. As such,
