Michael Goulet 413e350f87 Rollup merge of #98259 - jyn514:improve-obligation-errors, r=estebank ... Greatly improve error reporting for futures and generators in `note_obligation_cause_code` Most futures don't go through this code path, because they're caught by `maybe_note_obligation_cause_for_async_await`. But all generators do, and `maybe_note` is imperfect and doesn't catch all futures. Improve the error message for those it misses. At some point, we may want to consider unifying this with the code for `maybe_note_async_await`, so that `async_await` notes all parent constraints, and `note_obligation` can point to yield points. But both functions are quite complicated, and it's not clear to me how to combine them; this seems like a good incremental improvement.
