They're slightly different things. Your patch made sure that the test is 
skipped when ARB_compute_variable_group_size isn't available. And it's 
true that for the [require] section, you actually don't need to 
explicitly check for ARB_compute_shader on top of that, because a driver 
that advertises ARB_compute_variable_group_size must also advertise 
ARB_compute_shader.

My patch was mostly about adding the `#extension GL_ARB_compute_shader: 
enable` to the shaders themselves. I've pushed that now as well.

Cheers,
Nicolai
