39aca5ff9f Auto merge of #78399 - vn-ki:gsgdt-graphviz, r=oli-obk
make MIR graphviz generation use gsgdt

gsgdt [https://crates.io/crates/gsgdt] is a crate which provides an
interface for stringly typed graphs. It also provides generation of
graphviz dot format from said graph.

This is the first in a series of PRs on moving graphviz code out of rustc into normal crates and then implementating graph diffing on top of these crates.

3043a7b5d9 Improve warnings on incompatible options involving -Zinstrument-coverage
Adds checks for:

* `no_core` attribute
* explicitly-enabled `legacy` symbol mangling
* mir_opt_level > 1 (which enables inlining)

I removed code from the `Inline` MIR pass that forcibly disabled
inlining if `-Zinstrument-coverage` was set. The default `mir_opt_level`
does not enable inlining anyway. But if the level is explicitly set and
is greater than 1, I issue a warning.

The new warnings show up in tests, which is much better for diagnosing
potential option conflicts in these cases.

d9241640e8 Auto merge of #6435 - xFrednet:5552-false-positive-match-single-binding, r=ebroto
Fixing a false positive for the `match_single_binding` lint #5552

This is a fix for a false positive in the `match_single_binding` lint when using `#[cfg()]` on a branch. It is sadly a bit hacky but maybe the best solution as rust removes the other branch from the AST before we can even validate it. This fix looks at the code snippet itself and returns if it includes another thick arrow `=>` besides the one matching arm we found. This can again cause false negatives if someone has the following code:
```rust
match x {
    // => <-- Causes a false negative
    _ => 1,
}
```

I thought about making the code more complex and maybe validating against other things like the `#[cfg()]` macro but I believe that this is the best solution. This has basically switched the issue from a false positive to a false negative in a very specific case.

I'm happy to make some changes if you have any suggestions 🙃.

cargo dev fmt: don't format entire rustc repo if we ran ra_setup previously

It turns out that rustfmt sees a rustc repo that we pulled in as path dependency via `cargo dev ra-setup` as part of the tree and would try to format it :D

Of course we don't want this, so skip formatting if we see that we ran `ra-setup` previously.

Pass Clippy args also trough RUSTFLAGS

This removes a hack (\_\_CLIPPY_HACKERY\_\_) to add another one :)

It allows this workflow to work:
```terminal
cargo clippy                             # warning: empty `loop {}` wastes CPU cycles
cargo clippy -- -A clippy::empty_loop    # no warnings emitted
```

Before this change the new flag was not taken into consideration in cargo's fingerprint and the warning was emitted again. I guess that ideally we could add a specific env var for compiler wrapper arguments, but in the meantime this should do the job.

📌 Pin Clippy to a nightly 📌

changelog: Pin Clippy to a specific nightly version (No more master/custom toolchain required to compile Clippy)

Addresses partially #5561. As proposed there in [this comment](https://github.com/rust-lang/rust-clippy/issues/5561#issuecomment-623109095), this kicks off the process, to help us get acquainted with how the syncs should work, before working on improving the tooling.

Open questions:
* When performing a rustup, we will need to exclude the commits that were merged that same day, or else wait until that nightly is released. I did not update the documentation about this part, mainly because I'm not sure about how to do that.
* When should we perform the rustups now? My first idea is to do it at the same time we do the clippyups, to have a clear cadence and to avoid the two copies of the repo to diverge enough to make the process painful.
* Who does the rustups now? If we follow my previous idea and do both rustup and clippyup at the same time, it would be more work for `@flip1995` who currently does the clippyups. I would prefer to establish some kind of rotation to spead the work. Other ideas?
* I'm not sure if this affects the release process in any way.
* ???

`@rust-lang/clippy` thoughts?
