[PATCH] D32006: Mark invariant.group.barrier as inaccessiblememonly

Yes, you are right. I missed that in the tests. I will change it to have only inaccesiblememonly. It would be good to figure out a way to CSE 2 barriers if there is no write to memory between, because I don't see if it
is possible with current set of attributes. Fortunatelly it is not that important, we should not miss any important optimizations without that.
