[PATCH] D12310: Introducing llvm.invariant.group.barrier intrinsic

[Nick Lewycky via llvm-commits]

nlewycky added a comment.

Is there a LangRef change that introduces the barrier? If that's simply in a different review, then LGTM. Usually I'd ask for the feature and the LangRef change to land together, but it also makes sense to put the LangRef update for !invariant.group and @llvm.invariant.group.barrier together.
