I think we're close on the DAG safety belt (giving @RKSimon some time to look at the x86 tests I think).

...so hold off on this until that lands? Then we'd just convert directly to the xor sequence?

But I am curious - did you find this pattern in real code? I've never seen masked merge using or/nor before.
