I don't think there's much of a point to making them strings if it's not 
directly invoking the syncscope name for the backend. Realistically as long as 
we give them descriptive names we can just ignore ones that don't apply on 
various targets. Like right now you can use these scoped variants in x64 code 
but it has no effect. Either that or we could use logic to go to the next 
heirarchy level that makes sense. As always, naming stuff is hard.
