Based on Brecht's tests, we realize that OSL doesn't work at all with Cuda 8.0 (which didn't support the C++14 that we use), so we're raising the minimum to 9.0. And there are some flaky tests with 9 and 10, so we're making the recommended minimum be 11.0.
It's not our policy to change the minimum versions of dependencies on release branches, but I think we should backport this to the release branch. I believe what this change is doing is not removing actual support for old versions, but rather, correctly documenting what has been working (or not) for quite some time.
