[OpenCL] directly 4 8 bit int in integer causes compiling error

[westion717]

Hi, I find if use directly 4 8 bit int in integer as following link, it will cause compiling error (when the member of int is referred as .s0, .s1 later) in my opencl compiler provided by my vendor. I am wondering whether the paradigm is legal in the specific opencl spec version or it should be fixed to use char4 instead.

It looks wrong and should be fixed, I think.
