This is difficult.... Parsing and codegen are interleaved in clang.`ParseAST`
calls BackendConsumer::HandleTopLevelDecl and
BackendConsumer::HandleTranslationUnit ([call
stack](https://maskray.me/blog/2023-09-24-a-deep-dive-into-clang-source-file-compilation),
which do code generation.
I've introduced `yieldTo` and changed the timers. Updated the description.
