I don't mind abandoning this patch in favor of https://reviews.llvm.org/D29443, but if possible, i think you should break https://reviews.llvm.org/D29443 into several patches. I'm saying this because https://reviews.llvm.org/D29443 adds several new combines and it would be easier to review each combine in a separate patch with tests that show its goodness.
So it may turn out that after breaking https://reviews.llvm.org/D29443, this patch will end-up as the initial patch in a sequence. Does this make sense?
