Antonio Maiorano 08f4b557fc Implement atomicCompareExchangeWeak returning struct instead of vec2
Also fixed implementation of this atomic in GLSL. It was emitting code
that would not compile because, as for HLSL, we must pass in the
variable directly to atomic funcs, not via an in/out arg to a function.
