The ARB_buffer_storage spec is written against GL 4.3, but doesn't
seem to require it. I think that means you need to check for
ARB_SHADER_IMAGE_LOAD_STORE before using glMemoryBarrier().

I think I'd phrase that as "The ARB_buffer_storage spec requires …",
or just quote the relevant lines from the spec literally, and then add
a note that NVIDIA appears to enforce that, while Mesa doesn't.
