Hi JinGu,

I just read the discussion on cfe-dev, some comments:

> My colleague and I are implementing a transformation pass between LLVM IR and another IR and we want to keep the 3-component vector types in our target IR

Why can't you go back through the shuffle to find out that it comes from a vec3 -> vec4 transformation? Adding a flag here just for that seems very odd.
