This isn't just for OpenCL (actually we don't care about it in the context of OpenCL at all). We really are adding this as more of an extension for C99, where Android has used this in the past. In the case of OpenCL, I also don't know that it should be recognized as invalid, because it can be lowered to an appropriate construct on any implementation (since they all have to support regular 4-vectors).
