`redundant_closure` fixes
fixes#8548
A good chunk of the code is fixing false negatives. The old code banned any non late-bound regions from appearing in the callee's signature. The new version checks when the late-bound region is actually required.
changelog: Better track when a early-bound region appears when a late-bound region is required in `redundant_closure`.
changelog: Don't lint `redundant_closure` when the closure gives explicit types.
Rename and allow `cast_ref_to_mut` lint
This PR is a small subset of https://github.com/rust-lang/rust/pull/112431, that is the renaming of the lint (`cast_ref_to_mut` -> `invalid_reference_casting`).
BUT also temporarily change the default level of the lint from deny-by-default to allow-by-default until https://github.com/rust-lang/rust/pull/112431 is merged.

new lint: [`readonly_write_lock`]
Closes#8555
A new lint that catches `RwLock::write` calls to acquire a write lock only to read from it and not actually do any writes (mutations).

Now `option_env_unwrap` warns even if a variable isn't set at compiletime
Fixes#10742
changelog: Fix false negative where `option_env_unwrap` wouldn't warn if the env variable isn't set at compile-time.
Currently, Clippy, Miri, Rustfmt, and rustc all use an environment variable to
indicate that output should be blessed, but they use different variable names.
In order to improve consistency, this patch applies the following changes:
- Emit `RUSTC_BLESS` within `prepare_cargo_test` so it is always
available
- Change usage of `MIRI_BLESS` in the Miri subtree to use `RUSTC_BLESS`
- Change usage of `BLESS` in the Clippy subtree to `RUSTC_BLESS`
- Change usage of `BLESS` in the Rustfmt subtree to `RUSTC_BLESS`
- Adjust the blessable test in `rustc_errors` to use this same
convention
- Update documentation where applicable
Any tools that uses `RUSTC_BLESS` should check that it is set to any value
other than `"0"`.
Split some functions with many arguments into builder pattern functions
r? `@estebank`
This doesn't resolve all of the ones in rustc, mostly because I need to do other cleanups in order to be able to use some builder derives from crates.io
Works around https://github.com/rust-lang/rust/issues/90672 by making `x test rustfmt --bless` format itself instead of testing that it is formatted
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? :/
changelog: fix integration tests on ci
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 👍
