Restrict the use of the C++17 attribute to C++17 (at least as best we
can given the current __cplusplus definitions).
Without this, Clang triggers TONS of warnings about using a C++17
extension. I tried using LLVM_EXTENSION to turn these off and it doesn't
work.
Suggestions on a better approach are welcome, but at least this makes
the build usable for me again.
