ff0d44e45a Add imprecise_flops lint
Add lint to detect floating point operations that can be computed more
accurately at the cost of performance. `cbrt`, `ln_1p` and `exp_m1`
library functions call their equivalent cmath implementations which is
slower but more accurate so moving checks for these under this new lint.

b5e6d6db41 Auto merge of #5134 - flip1995:snippet_block, r=phansch
Make it possible to correctly indent snippet_block snippets

This adds a `indent_relative_to` arg to the `{snippet,expr}_block` functions. This makes it possible to keep the correct indentation of block like suggestions.

In addition, this makes the `trim_multiline` function private and adds a `indent_of` function, to get the indentation of the first line of a span.

The suggestion of `needless_continue` cannot be made auto applicable, since it would be also necessary to remove code following the linted expression. (Well, maybe it is possible, but I don't know how to do it. Expanding the suggestion span to the last expression, that should be removed didn't work)

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.

Fix syntax highlighting of code fences

The documentation for RESULT_EXPECT_USED includes this code:

    let res: Result<usize, ()> = Ok(1);
    res?;
    # Ok::<(), ()>(())

Because the code fence didn't start with `rust`, the code wasn't highlighted and the line starting with `#` was displayed on the website. This is now fixed.

EDIT: I noticed that highlighting for some other lints is broken as well. It only works if the code fence looks like this:

````markdown
```rust
// ..
```
````

However, many code blocks were ignored. I un-ignored most code blocks and made them compile by adding hidden code with `#`. While doing so, I found two mistakes:

```rust
opt.map_or(None, |a| a + 1)
// instead of
opt.map_or(None, |a| Some(a + 1))
```
and

```rust
fn as_str(self) -> &str
// instead of
fn as_str(self) -> &'static str
```

Fix syntax highlighting of code fence
The documentation for RESULT_EXPECT_USED includes this code:

    let res: Result<usize, ()> = Ok(1);
    res?;
    # Ok::<(), ()>(())

Because the code fence didn't start with `rust`, the code wasn't highlighted and the line starting with `#` was displayed on the website. This is now fixed.

changelog: dont fire `possible_missing_comma` if intendation is present

I suspect there is already a utils function for indentation (but searching indent didn't yield a function for that), and my solution is certainly not universal, but it's probably the best we can do.

changelog: add size threshold for the `vec_box` lint, currently 4096 bytes (one page) (subject to change). Closes #3547.

diff is a little bit confusing due to some refactoring (moving free functions to lint struct functions), relevant portion is [this](https://github.com/rust-lang/rust-clippy/compare/master...Areredify:vec_box_threshold?expand=1#diff-1096120ca9143af89dcc9175ea92b54aR294-R298).

Match wild err arm improvements

This lint should trigger on other identifiers which have `_` prefix (such as `_e`) and only if they are unused in the panic block.

_Note_: the `is_unused` function is greatly inspired from `pat_is_wild` function in [loops lints](43ac9416d9/clippy_lints/src/loops.rs (L1689)).
I've been considering doing some refactoring, maybe in utils. Maybe this PR or a new one. What do you think ?

Fix ICE on `unsound_collection_transmute`

Fixes #4968

Check if `Ty`s are normalizable. It might show hidden false negative, I'm not sure.
Also, the regression tests are placed on two dirs, so move them to `/crashes`. I think it will be easier to find the right place.

84a60c3186 Prevent replace_consts lint within match patterns
Currently `replace_consts` lint applies within match patterns but
the suggestion is incorrect as function calls are disallowed in
them. To fix this we prevent the lint from firing within patterns.

8db319f957 Use mem::take instead of mem::replace when applicable
`std::mem::take` can be used to replace a value of type `T`
with `T::default()` instead of `std::mem::replace`.
