Add the from_str_radix_10 lint
changelog: added the new `from_str_radix_10` which sometimes replaces calls to `primitive::from_str_radix` to `str::parse`
This is ready to be merged, although maybe the category should be `pedantic` instead of `style`? I'm not sure where it fits better.
Closes#6713.

lintcheck: parallelize
By default we use a single thread and one target dir as before.
If `-j n` is passed, use `n` target dirs and run one clippy in each of them.
We need several target dirs because cargo would lock them for a single process otherwise which would prevent the parallelism.
`-j 0` makes rayon use $thread_count/2 (which I assume is the number of physical cores of a machine) for the number of threads.
Other change:
Show output of clippy being compiled when building it for lintcheck (makes it easier to spot compiler errors etc)
Show some progress indication in the "Linting... foo 1.2.3" message.
Sort crates before linting (previously crates would be split randomly between target dirs, with the sorting, we try to make sure that even crates land in target dir 0 and odd ones in target dir 1 etc..)

changelog: parallelize lintcheck with rayon
Use rayon to figure out the threadcount and half that for core count.
For each core, create a target dir that is used.
Otherwise, when running multiple clippys with the same target-dir, cargo would lock the dir and prevent parallelism.
This way we can run multiple clippys at the same time (on root crates) but we sacrifice cache-hits (when we already cargo-checked crate-deps).

Fix lintcheck by excluding checked crates from workspace
r? `@matthiaskrgr` cc `@camsteffen`
So `exclude` doesn't work with glob patterns, but it turns out that it works with `starts_with`.

Lintcheck and an options for command line options
Make it possible to add command line options to the clippy invocation of the lintcheck-tool

I found that this will be really helpful if we use a separate repository and want to maintain a all-lints-passing list of crates. See my early experimentation here: https://github.com/flip1995/clippy-lintcheck
```
git submodule update --init
cargo run -- --mode=all
```
Will run the lintcheck tool on all the specified crates in `config/` in that repository.
New lint: default_numeric_fallback
fixes#6064
r? `@flip1995`
As we discussed in [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20.236064/near/224647188) and [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20clippy.236064/near/224746333), I start implementing this lint from the strictest version.
In this PR, I'll allow the below two cases to pass the lint to reduce FPs.
1. Appearances of unsuffixed numeric literals in `Local` if `Local` has a type annotation, for example:
```rust
// Good.
let x: i32 = 1;
// Also good.
let x: (i32, i32) = if cond {
(1, 2)
} else {
(2, 3)
};
```
2. Appearances of unsuffixed numeric literals in args of `Call` or `MethodCall` if corresponding arguments of their signature have concrete types, for example:
```rust
fn foo_mono(x: i32) -> i32 {
x
}
fn foo_poly<T>(t: T) -> t {
t
}
// Good.
let x = foo_mono(13);
// Still bad.
let x: i32 = foo_poly(13);
```

more lintcheck updates
* do some refactoring and renaming here and there
* add comments to functions
* fix bug where git repos would not get checked out to the proper commits (cmd was not actually run in repo directory 😅 )
* print warnings if we can't clone or check out a git repo
* filter out noise from cargo-metadata errors and lint messages that contained absolute file paths (these would change with every pinned-nightly bump, polluting the logs)

Upgrade compiletest-rs to 0.6 and tester to 0.9
These updates allow us to specify multiple testnames for `TESTNAME` by
providing a comma separated list of testnames.
The new version of compiletest-rs also includes `bless` support, but is
not enabled with this PR.
