[Beignet] [PATCH V2 2/2] utests: add an utest for mix

[Pan, Xiuli]

Thanks for you remind about the INF problem, the spec does not talk about the <x> and <y>, so I think we may consider it more.
This is surely a problem, so how about mad? It can also calculate the mix but may need some more instruction, can it handle the INF problem?

I don't know what OpenCL's spec says about this issue, but you should be aware that Gen's LRP instruction does not return INFINITY when <x> or <y> is INFINITY.
