My understanding was `IntrConvergent` prevented optimizations to move this
instruction into another control-flow, but could change the order in a given
BB/flow, but from the few tests I did, it seems those are not optimized anyway
(even dead-stores).
So for now let's go with `IntrConvergent` and `IntrNoMem`, and if we have a
repro/issue in the future, we'll know for sure.
