In the lambda we are now returning the remark by value so we need to preserve its type in the insertion operator. This requires making the insertion operator generic. I've also converted a few cases to use the new API. It seems to work pretty well. See the LoopUnroller for a slightly more interesting case. llvm-svn: 313691
