Currently mirrors are stored in the rust-lang-ci2 S3 bucket along with CI toolchains. This is problematic for multiple reasons: - CI IAM credentials are allowed to both edit and delete those files. A malicious user gaining access to those credentials would be able to change our mirrored dependencies, possibly backdooring the compiler. - Contents of the rust-lang-ci2 bucket are disposable except for the mirrors' content. When we implement backups for S3 buckets we'd have to replicate just that part of the bucket, complicating the backup logic and increasing the chance of mistakes. A standalone bucket will be way easier to backup. This commit switches our CI to use the new rust-lang-ci-mirrors bucket.

This commit prohibits return position `impl Trait` types that "inherit lifetimes" from the parent scope. The intent is to forbid cases that are challenging until they can be addressed properly.
This allows us to record "fresh" lifetime names for cases like `impl Foo<'_>`.
We now always make fresh lifetimne parameters for all elided
lifetimes, whether they are in the inputs or outputs. But then
we generate `'_` in the case of elided lifetimes from the outputs.
Example:
```rust
async fn foo<'a>(x: &'a u32) -> &u32 { .. }
```
becomes
```rust
type Foo<'a, 'b> = impl Future<Output = &'b u32>;
fn foo<'a>(x: &'a u32) -> Foo<'a, '_>
```
This was causing us to incorrectly think the lifetimes were already declared on the scope for the nested item, when in fact they are not inherited.
Recently we encountered multiple spurious failures where the crates.io certificate was reported as expired, even though it's currently due to expire in a few months. This adds some code to our CI to check for clock drifts, to possibly find the cause or rule out a bad VM clock.
The slash and quotes in ?/“Kleene” appeared to define “Kleene” as the name for the ? operator, which is not the case. Rust has three Kleene operators *, +, ?. (Pointed out by /u/Sharlinator on Reddit.) Signed-off-by: Anders Kaseorg <andersk@mit.edu>
Do not ICE when synthesizing spans falling inside unicode chars Fix rust-lang#61226.

Provide map_ok and map_err method for Poll<Option<Result<T, E>>> Currently `map_ok` and `map_err` methods are given for `Poll<Result<T, E>>`. This PR adds these methods for `Poll<Option<Result<T, E>>>` as they are helpful in stream building code.
…tril RELEASES.md: ? is one of three Kleene operators The slash and quotes in ?/“Kleene” appeared to define “Kleene” as the name for the `?` operator, which is not the case. Rust has three Kleene operators `*`, `+`, `?`. ([Pointed out](https://www.reddit.com/r/rust/comments/cprt0z/rust_1370_prerelease_testing/ewr90y3/) by /u/Sharlinator on Reddit.)
