67a9f20c91 Fix map_clone bad suggestion
`cloned` requires that the elements of the iterator must be references. This
change determines if that is the case by examining the type of the closure
argument and suggesting `.cloned` only if it is a reference. When the closure
argument is not a reference, it suggests removing the `map` call instead.

A minor problem with this change is that the new check sometimes overlaps
with the `clone_on_copy` lint.

Fixes #498

Missing docs: don't require documenting Global Asm items.

global_asm! items cannot be documented, the lint still gets triggered after adding documentation to the macro invocation. Furthermore, even if we could add documentation to the AST node, rustdoc doesn't render it anyways.

ec1a6cb442 Auto merge of #3658 - detrumi:add-several-run-rustfix-annotations, r=phansch
Add several run rustfix annotations

Adds `run-rustfix` to 18 of the tests from the tracking issue #3630.
Each test has its own commit, to make reviewing easier (hopefully this is easier to review than 18 separate PRs).

## Changes
- `cfg_attr_rustfmt`: Custom inner attributes are unstable. Let's disable the lint for inner attributes until [#54726](https://github.com/rust-lang/rust/issues/54726) stabilizes
- `collapsible_if`: unrelated cyclomatic_complexity warning that can be ignored
- `duration_subsec`: Simply needed `#![allow(dead_code)]`
- `excessive_precision`: Fixed by `#!allow(dead_code,unused_variables)`
- `explicit_write`: Fixed by `#![allow(unused_imports)]`
- `inconsistent_digit_grouping`: Avoid triggering `clippy::excessive_precision` lint
- `infallible_destructuring_match`: Fixed by `#![allow(dead_code, unreachable_code, unused_variables)]`
- `into_iter_on_ref`: Triggered unrelated `clippy::useless_vec` lint
- `large_digit_groups`: Avoid triggering `clippy::excessive_precision` lint
- `map_clone`: Fixed by `#![allow(clippy::iter_cloned_collect)]`
- `mem_replace`: Suggestion causes import to be unused, fixed by `#![allow(unused_imports)]`
- `precedence`: Allow some unrelated lints, and change out-of-range `0b1111_1111i8` literal
- `redundant_field_names`: Allow dead code, and remove stabilized feature toggles
- `replace_consts`: Fixed by `#![allow(unused_variables)]`
- `starts_ends_with`: Fixed by `#![allow(unused_must_use)]`
- `types`: Fixed by `#![allow(dead_code, unused_variables)]`
- `unit_arg`: Fixed by `#[allow(unused_must_use)]`
- `unnecessary_fold`: Fixed by adding type annotations and adding `#![allow(dead_code)]`

5b8496603c Auto merge of #3640 - detrumi:nested_use_self, r=flip1995
Restrict `use_self` on nested items

Fixes #3637
Fixes #3463

These changes make it so that nested items aren't visited any more by the `use_self` lint.

I think visiting nested items should be possible (so that it uses a different `item_path` for the nested item), but I'm not sure whether it's viable and what the best approach would be.
- Can `item_path` be changed to a new `Self` path before visiting the item, and then changing it back afterwards?
- Alternatively, could a new visitor be created, re-using `check_trait_method_impl_decl`?

cast_ref_to_mut lint

I see this pattern way too often, and it's completely wrong. In fact, due to how common this incorrect pattern is, [the Rustonomicon specifically points this out](https://doc.rust-lang.org/nomicon/transmutes.html).

> - Transmuting an & to &mut is UB
>   - Transmuting an & to &mut is always UB
>   - No you can't do it
>   - No you're not special

This is my first lint.

d264e406be Auto merge of #3627 - detrumi:use_self_local_macro, r=phansch
Trigger `use_self` lint in local macros

Closes #2098

The test currently only covers local macros. #2098 suggested this:
> You could add the macro in question into the `mini_macro` subcrate

But that doesn't work for a `macro_rules`:
```
error: cannot export macro_rules! macros from a `proc-macro` crate type currently
```

So I suggest leaving out the test for external macros, as using `in_external_macro` seems straigtforward enough. Alternatives would be to use to add an additional crate (overkill if you ask me), or test with a `proc-macro`.

Fix if_same_then_else false positive

This fixes false positive in #3559.
The problem was that `SpanlessEq` does not check patterns in declarations. So this two blocks considered equal.
```rust
if true {
    let (x, y) = foo();
} else {
   let (y, x) = foo();
}
```
Not sure if the proposed change is safe as `SpanlessEq` is used extensively in other lints, but I tried hard to come up with counterexample and failed.

Implements lint for order comparisons against bool (#3438)

As described on issue #3438, this change implements linting for `>` and `<` comparisons against both `boolean` literals and between expressions.

Lint redundant clone of fields

Makes `redundant_clone` warn on unnecessary `foo.field.clone()` sometimes (it can detect an unnecessary clone only if the base of projection, `foo` in this case, is not used at all after that). This is enough for cases like `returns_tuple().0.clone()`.

Downgrade unsafe_vector_initialization to restriction
This lint looks for:

    let mut vec = Vec::with_capacity(len);
    vec.set_len(len);

The suggested replacement is `vec![0; len]`.

This is far too opinionated to be a deny-by-default lint because the performance
characteristics of the suggested replacement are totally different.

I am not convinced that this lint has value beyond what deny(unsafe_code) gives
you. Unsafe code is unsafe but please don't deny-by-default lint it if that's
the only reason.
