[Clang] [CodeComplete] Cannot complete C++20 keywords

[16bit-ykiko]

The issue caught my attention a long time ago, but I don't expected that no one had reported it. The SemaComplete won't complete C++20 keywords(concept, co_await, co_return, ...).

if I type con^, SemaComplete only returns const and contexpr as the two candidates, in the namespace context. This can be verified by the code-complete-at command.

And I’m interested in this issue. Could I give it a try and work on resolving it?
