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

[Piotr Padlewski via Phabricator via llvm-commits]

Prazek added a comment.

Because now barrier is considered as writing memory, I marked it's argument as nocapture. I am not sure if it is correct, since barrier returns it's pointer. Does it mean that it outlives the barrier?
