Adds the minimial repro test case from #85360. The fix for #85360 was
supposed to be #85868 however the repro was resolved in the 2021-07-05
nightly while #85360 didn't land until 2021-09-03. The reason for that
is d34a3a401b **also** resolves that
issue.
To test if #85868 actually fixes#85360, I reverted
d34a3a401b and found that #85868 does
indeed resolve#85360.
With that question resolved, add a test case to our incremental test
suite for the original Ok(EvaluatedToOkModuloRegions) ICE.
Thanks to @lqd for helping track this down!
rustdoc: Remove Clean impls for tuples
This PR removes all nine Clean impls on tuples, converting them to
functions instead.
The fact that these are impls causes several problems:
1. They are nameless, so it's unclear what they do.
2. It's hard to find where they're used apart from removing them and
seeing what errors occur (this applies to all Clean impls, not just
the tuple ones).
3. Rustc doesn't currently warn when impls are unused, so dead code
can accumulate easily (all Clean impls).
4. Their bodies often use tuple field indexing syntax (e.g., `self.1`)
to refer to their "arguments", which makes reading the code more
difficult.
As I noted, some of these problems apply to all Clean impls, but even
those problems are exacerbated by the tuple impls since they make
general understanding of the code harder.
Converting the impls to functions solves all four of these problems.

it to a function instead.

Reintroduce `into_future` in `.await` desugaring
This is a reintroduction of the remaining parts from https://github.com/rust-lang/rust/pull/65244 that have not been relanded yet.
This isn't quite ready to merge yet. The last attempt was reverting due to performance regressions, so we need to make sure this does not introduce those issues again.
