We saw some good looking codesize decreases from this, by the way. Just to add to the "this patch does good" side of the argument :)
For lifetime.end, if we start producing llvm.lifetime.end(phi(x, y, z)) then I could see that potentially being worse. I have no evidence of that happening though. And it may even be better if it allows further sinking.
