This fixes the first error reported in issue #3410.

3407: Fix `possible_missing_comma` false positives r=oli-obk a=mikerite
`possible_missing_comma` should only trigger when the binary operator has
unary equivalent. Otherwise, it's not possible to insert a comma without
breaking compilation. The operators identified were `+`, `&`, `*` and `-`.
This fixes the specific examples given in issues #3244 and #3396
but doesn't address the conflict this lint has with the style of starting
a line with a binary operator.

3408: RIIR update lints: Add check mode (update_lints.py rewrite complete) r=oli-obk a=phansch
This finishes up the rewrite of `update_lints.py` in Rust. More
specifically, this
* adds the `--check` flag and handling to clippy_dev
* tracks file changes over the different calls to `replace_region_in_file`
* only writes changes to files if the `--check` flag is *not* used
* runs `./util/dev update_lints --check` on CI instead of the old script
* replaces usage of the `update_lints.py` script with an error
`./util/dev update_lints` behaves 99% the same as the python script.
The only difference that I'm aware of is an ordering change to
`clippy_lints/src/lib.rs` because underscores seem to be sorted
differently in Rust and in Python.

3353: float support added for mistyped_literal_suffixes lint r=mikerite a=Maxgy
I implemented the mistyped_literal_suffixes lint for float literals.
```
#![allow(unused_variables)]
fn main() {
let x = 1E2_32;
let x = 75.22_64;
}
```
Given the above, the additional check suggests the variables to be written as `let x = 1E2_f32` and `let x = 75.22_f64`.
Fixes#3167

3399: RIIR update lints: Generate modules section and lint group sections r=flip1995 a=phansch
This adds the last missing parts of the generating code.

3344: Added lints `into_iter_on_ref` and `into_iter_on_array`. r=phansch a=kennytm
Fixes#1565.
`into_iter_on_array` is a correctness lint against `into_iter()` on `[T; n]` and `PathBuf` (please provide a concise noun that covers both types 🙃).
`into_iter_on_ref` is a style lint against `into_iter()` on `&C` where `C` is `[T]`, `Vec<T>`, `BTreeSet<T>` etc.
Both suggests replacing the `into_iter()` with `iter()` or `iter_mut()`.
`into_iter_on_array` is a correctness lint since it is very likely the standard library would provide an `into_iter()` method for `[T; n]` (rust-lang/rust#25725) and existing type inference of `[a, b, c].into_iter()` will be broken. `PathBuf` is also placed under this lint since `PathBuf::into_iter` currently doesn't exist and it makes some sense to implement `IntoIterator` on it yielding `OsString`s.

3161: New lint: Unknown clippy lints r=phansch a=flip1995
This is the Clippy version of the `rustc` lint `unknown_lints`. The behavior of this lint is pretty much the same.
Before this is merged a small change in the compiler needs to be done: `CheckLintNameResult` needs to be public. See rust-lang/rust#54106
