Improve compile_test and dogfood tests
* Hopefully this finally resolves the "multiple matching crates" error, e.g. #4015
* This handle some convenient CARGO env like CARGO_TARGET_DIR and CARGO_BUILD_TARGET

Prevent failing to restart setup-toolchain
If `rustup-toolchain-install-master` fails to install master
toolchain (in case `rustup update` executes at the same remove the
tmp directory), `cargo search` (which use master toolchain after
`rustup override` command) will fail. This leads to setup-toolchain
fails too.

Add new lint: match with a single binding statement
This lint catches `match` statements that binds to only one block and could be rewritten using a simple `let` statement.
Lint name: MATCH_SINGLE_BINDING
fixes: #3664
changelog: add lint for match with single binding statement
Use `checked_sub` to avoid index out of bounds
(Fixes) #4681 (possibly)
The issue likely occurs due to `lit_snip.len() < suffix.len() + 1`. You can see similar backtrace to change it to `lit_snip.len() - suffix.len() - 1000` or something then run `cargo test --release`.
But I couldn't come up with the test so I'd leave the issue open if we want.
changelog: Fix potential ICE in `misc_early`
Tweak documentation in `multiple_crate_versions`
This example isn't reproducible now since `ctrlc` upgrades `winapi` to `0.3.x` in `3.1.1`. We should pin their versions to trigger lint correctly.

Don't trigger [debug_assert_with_mut_call] on debug_assert!(_.await)

changelog: Don't trigger [`debug_assert_with_mut_call`] on `debug_assert!(_.await)` and move it to nursery.
Deprecate util/dev in favor of cargo alias
This means one less shell script and a bit more cross-platform support
for contributors.
If you've been using `./util/dev` before, this now becomes `cargo dev`.
The key part of this change is found in `.cargo/config` where an alias for calling the `clippy_dev` binary is defined.
