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`.

`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.

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

3397: UI test cleanup: Extract expect_fun_call tests r=matthiaskrgr a=phansch
Note that the new stderr file does not include a `shadow-unrelated`
error, because the new UI test file does not use `#![warn(clippy::all)]`

3388: RIIR update lints: Generate deprecated lints r=phansch a=phansch
The update script now also generates the 'register_removed' section in
`clippy_lints/src/lib.rs`.
Also, instead of using `let mut store ...`, I added a new identifier
line so that the replacement will continue to work in case `let mut
store ...` ever changes.

3389: ci: when installing rust-toolchain-installer-master, install it in debug mode to save some time on ci. r=phansch a=matthiaskrgr
the compiletime optimizations probably take longer than the speedup we get when executing the optimized binary vs debug build.
