Fix#4033 search_is_some
Fixes#4033.
Suggest `any(|x| ..)` instead of `any(|&x| ..)` for `find(|&x| ..).is_some()` (Lint [search_is_some](https://rust-lang.github.io/rust-clippy/master/index.html#search_is_some))
FnDecl of `find`:
```rust
fn find<P>(&mut self, mut p: P) -> Option<Self::Item> where
P: FnMut(&Self::Item) -> bool
```
FnDecl of `any`:
```rust
fn any<F>(&mut self, mut f: F) -> bool where
F: FnMut(Self::Item) -> bool
```
If match on `|&_|` in closure of `find`, only use `|_|` in the suggestion.
PS. It's the first time that I have used the `hir` API, please correct me if there is any mistake 😺
useless_let_if_seq handle interior mutability
fixes#3043
This passes all tests, including a new one specifically dealing with a type with interior mutability. The main thing I'm unsure of is whether the span I used in the call to `is_freeze` is the most appropriate span to use, or if it matters.
Add lints for find_map
changelog: adds lints for find_map and filter_map_next. Closes issue #3474
Hope I got everything correctly this time! Let me know if I missed something.

Suggest .copied() for map_clone on iterators too

Fix breakage due to rust-lang/rust#60225
Wrote this up before I saw that Manish already started on a fix in #4038. It no doubt contains errors. Feel free to close.
Do not trigger redundant_closure for non-function types
fixes#3898
Added a check for the entity being called in the closure body to be a FnDef. This way lint does not trigger for ADTs (Box) but I'm not sure if it's correct and not too restrictive.

Thank you for making Clippy better!
We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.
If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- [ ] Followed [lint naming conventions][lint_naming]
- [ ] Added passing UI tests (including committed `.stderr` file)
- [ ] `cargo test` passes locally
- [ ] Executed `util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `cargo fmt`
Note that you can skip the above if you are just opening a WIP PR in

changelog: Fix false positive in `redundant_closure` pertaining to non-function types
Only run AppVeyor on r+, try and the master branch
As it is right now, there is only one worker available in the `rust-lang-libs`
AppVeyor project and there are other repos as well that we share this worker
with. This has been a problem for us because we sometimes hit a bors timeout if there
are too many builds queued up.
To improve the situation, I think we could try to use AppVeyor a bit less
often. The average PR is not going to break windows related things anyway, so
it should be fine to run it on r+/try/master only.
changelog: none
