Support for clang-8, drop support for clang-6

Clang-8 dropped APIs that were deprecated in Clang-7.

If you feel the need to support Clang-6 we are open for it, just send a PR with the appropriate #ifdef conditions to handle the APIs that didn't exist on Clang-6 yet.

We are not using Clang-6 anymore, but we are not fundamentally opposed to supporting it if someone has a relevant need.
