ChromeOS/ARC++ currently disables GLES 3.1 on i965 because we haven't
passed all the dEQP tests for it.  So, we support the functionality,
but they're using GLES 3.0 contexts.  I'm guessing that's why they hit
this and I haven't.

They could probably disable the bit too, but checking whether the
feature is actually exposed seems pretty reasonable.
