So I've done my best to test this. These are the diffs between the
glxinfo reports before and after on radeonsi and i965

I'm not aware of anything that uses OpenGL 3.1 Compat or the
ARB_compatability extension, but if you know of anything I'll test it
directly

Should i965 show the extra extensions or a higher compat version as
well as the bump to the GLSL version?

My games continue to work after this change is applied
