----------------
I see a lot of VP intrinsic added, but I'm a little confused about how to use these intrinsics. 

I would hazard a guess that the next step is to construct the [[ https://www.llvm.org/docs/Proposals/VectorPredication.html#id5 | IR-level VP intrinsic]]?  Is there an initial patch or discussion?
