Fix integration tests #2
fix integration tests.
It turned out that the following tests fail to build at all:
chalk, combine, stdarch and hyper.
This is often a problem of passing `--all-targets --all-features`, in case of combine though, outdated deps were to blame.
I have opened tickets against combine and rustfmt
https://github.com/rust-lang/rustfmt/issues/5859https://github.com/Marwes/combine/issues/357
should we just remove the other failing repos? :/

Add *no merge policy* note via rustbot
I just found out that ``@rustbot`` can automatically add a note about our *no-merge commits* policy, if it detects a merge commit: https://forge.rust-lang.org/triagebot/no-merge.html
Funnly enough, I found this while writing documentation for Marker. ``@rustbot`` is a cool tool 👍

Make std tests pass on newer Android
Newer versions of Android forbid the creation of hardlinks as well as Unix domain sockets in the /data filesystem via SELinux rules, which causes several tests depending on this behavior to fail. So let's skip these tests on Android if we see an EACCES from one of these syscalls. To achieve this, introduce a macro with the horrible name of or_panic_or_skip_on_android_eacces (better suggestions welcome) which skips (returns from) the test if an EACCES return value is seen on Android.
add tidy check that forbids issue-XXXX and ice-XXXX test filenames
Helps with #113345 by preventing any future tests with non-descriptive names from being added.
This PR only checks modified ui test files because there are far too many existing problematic tests to be fixed at once:
3063/15424 (~19.86%) `*.rs` ui test files match `^issue[-_ ]?\d+$`.
Another 1349 files, totaling ~28.60% of all ui test files, contain that pattern in addition to some other text, where they should probably omit it in favor of a comment.
note: between the creation of this PR and 2023-07-25 (14 days), 10 more tests were added that failed this check.

It doesn't really matter what the `desugar_doc_comments` argument is
here, because in practice we never look ahead through doc comments.
Changing it to `cursor.desugar_doc_comments` will allow some follow-up
simplifications.
new unstable option: -Zwrite-long-types-to-disk
This option guards the logic of writing long type names in files and instead using short forms in error messages in rustc_middle/ty/error behind a flag. The main motivation for this change is to disable this behaviour when running ui tests.
This logic can be triggered by running tests in a directory that has a long enough path, e.g. /my/very-long-path/where/rust-codebase/exists/
This means ui tests can fail depending on how long the path to their file is.
Some ui tests actually rely on this behaviour for their assertions, so for those we enable the flag manually.
`AtomicBool` is defined to have the same layout as `bool`, which means
that we guarantee that it has a size of 1 byte. However on certain
architectures such as RISC-V, LLVM will emulate byte atomics using a
masked CAS loop on an aligned word.
We can take advantage of the fact that `bool` only ever has a value of 0
or 1 to replace `swap` operations with `and`/`or` operations that LLVM
can lower to word-sized atomic `and`/`or` operations. This takes
advantage of the fact that the incoming value to a `swap` or
`compare_exchange` for `AtomicBool` is often a compile-time constant.

CI: split nested GHA groups instead of panicking
Bootstrap uses Github Actions groups to reduce clutter in CI job output. However, GHA doesn't support group nesting, and currently, when a group would be nested, bootstrap would panic. This is causing intermittent CI failures, because it's not trivial to make sure that groups won't be nested, and subtle changes in bootstrap (or even in caches being present) can cause nesting.
This PR changes the logic so that groups are never nested. Instead, when a group would be nested, the previous group is ended, and only then is the subgroup started. When the subgroup finishes, it will then restart any previously ended parent group.

Double check that hidden types match the expected hidden type
Fixes https://github.com/rust-lang/rust/issues/113278 specifically, but I left a TODO for where we should also add some hardening.
It feels a bit like papering over the issue, but at least this way we don't get unsoundness, but just surprising errors. Errors will be improved and given spans before this PR lands.

Don't say that a type is uncallable if its fn signature has errors in it
This is fallout from #106309, where we don't consider param-env candidates that reference errors because they unify with everything. This means, however, that we don't consider an APIT like `impl Fn(MissingType)` isn't considered to implement `Fn`, for example.
We can double-check that with a weaker heuristic [`extract_callable_info`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_typeck/fn_ctxt/struct.FnCtxt.html#method.extract_callable_info), and suppress the knock-down error using that.

- fix(cargo-credential): should enable feature `serde/derive` (rust-lang/cargo#12396)
- fix: encode URL params correctly for SourceId in Cargo.lock (rust-lang/cargo#12280)
- docs: format config override caveat as a note (rust-lang/cargo#12392)
- credential provider implementation (rust-lang/cargo#12334)
- feat(crates-io): expose HTTP headers and Error type (rust-lang/cargo#12310)
- chore: Don't update test data (rust-lang/cargo#12380)
- fix: only skip mtime check on `~/.cargo/{git,registry}` (rust-lang/cargo#12369)
- Update docs for artifact JSON debuginfo levels. (rust-lang/cargo#12376)
Since rust-lang/cargo#12334 makes built-in credential providers part of the cargo binary, it's no longer needed to build them in bootstrap.
