The only part of Lex you'll ever need to touch (unless you're extending the preprocessor) is TokenKinds.td, which actually lives in Basic. It defines the special tokens and keywords that exist in Clang. If you need a new keyword, you simply add it there.
Everything else should probably go into Parser, Sema and CodeGen.
