As for using asSlice as an alignment check. We don't have an asSlice method in MS which takes an element count, so we would also have to create a SequenceLayout on the fly. Not sure what to do... kinda feels like we need a reinterpret overload that takes an alignment, or another more convenient way to check alignment.

I think in principle checking alignment here is a good idea, since we're 'sanitizing' a raw address here, and an alignment check is a good way to catch corrupt pointers.
