After some more testing, it seems like my hypothesis about the issue was wrong. I think the real problem was that WWM wasn't being disabled in the face of control flow like I intended it to, and then stuff was getting messed up because inactive lanes were enabled when the code assumed they weren't. At least, that's my theory for now. I'm going to update https://reviews.llvm.org/D34717 to fix that.
