Lint: filter(Option::is_some).map(Option::unwrap)

Fixes #6061

*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog:
* add new lint for filter(Option::is_some).map(Option::unwrap)

First Rust PR, so I'm sure I've violated some idioms. Happy to change anything.

I'm getting one test failure locally -- a stderr diff for `compile_test`. I'm having a hard time seeing how I could be causing it, so I'm tentatively opening this in the hopes that it's an artifact of my local setup against `rustc`. Hoping it can at least still be reviewed in the meantime.

I'm gathering that since this is a method lint, and `.filter(...).map(...)` is already checked, the means of implementation needs to be a little different, so I didn't exactly follow the setup boilerplate. My way of checking for method calls seems a little too direct (ie, "is the second element of the expression literally the path for `Option::is_some`?"), but it seems like that's how some other lints work, so I went with it. I'm assuming we're not concerned about, eg, closures that just end up equivalent to `Option::is_some` by eta reduction.

disable upper_case_acronyms for pub items - enum edition

Fixes https://github.com/rust-lang/rust-clippy/issues/6803 (again... 😅  )

My previous fix did not work for enums because enum variants were checked separately in the `check_variant` function but it looks like we can't use that because we can't tell if the enum the variants belong to is declared as public or not (it always said `Inherited` for me)

I went and special-cased enums and iterated over all the variants "manually", but only, if the enums is not public.

a57a8c3058 Remove (lots of) dead code 
Found with https://github.com/est31/warnalyzer.

Dubious changes:
- Is anyone else using rustc_apfloat? I feel weird completely deleting
  x87 support.
- Maybe some of the dead code in rustc_data_structures, in case someone
  wants to use it in the future?
- Don't change rustc_serialize

  I plan to scrap most of the json module in the near future (see
  https://github.com/rust-lang/compiler-team/issues/418) and fixing the
  tests needed more work than I expected.

TODO: check if any of the comments on the deleted code should be kept.

#5733 is only fixed in the normal case, if different paths are used for the variants then the same problem will occur. It's cause by `def_path_str` returning an utterly useless result. I haven't dug into why yet.

For #6604 there should be some discussion before accepting this. It's easy enough to change the message rather than disable the lint for `Option` and `Result`.

b62694b08f Auto merge of #82122 - bstrie:dep4real, r=dtolnay 
Deprecate `intrinsics::drop_in_place` and `collections::Bound`, which accidentally weren't deprecated

Fixes #82080.

I've taken the liberty of updating the `since` values to 1.52, since an unobservable deprecation isn't much of a deprecation (even the detailed release notes never bothered to mention these deprecations).

As mentioned in the issue I'm *pretty* sure that using a type alias for `Bound` is semantically equivalent to the re-export; [the reference implies](https://doc.rust-lang.org/reference/items/type-aliases.html) that type aliases only observably differ from types when used on unit structs or tuple structs, whereas `Bound` is an enum.

ast/hir: Rename field-related structures

I always forget what `ast::Field` and `ast::StructField` mean despite working with AST for long time, so this PR changes the naming to less confusing and more consistent.

- `StructField` -> `FieldDef` ("field definition")
- `Field` -> `ExprField` ("expression field", not "field expression")
- `FieldPat` -> `PatField` ("pattern field", not "field pattern")

Various visiting and other methods working with the fields are renamed correspondingly too.

The second commit reduces the size of `ExprKind` by boxing fields of `ExprKind::Struct` in preparation for https://github.com/rust-lang/rust/pull/80080.

fixes #6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.

Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken:  `&self` or `&mut self`.

Improve needless_borrowed_ref docs

changelog: none

I think "borrowed ref" is a confusing description for this lint. Destructuring a reference is the opposite of borrowing. So I updated the wording throughout the docs. Unfortunately this nit applies to the name of the lint itself, but I won't bother changing that. One motivation for these changes is to clarify the difference between this lint and `needless_borrow` (they are actually quite different). Let me know if I need to clarify anything or if you disagree with any changes.

Refactor casts lint

Ref: #6724

Changes:
1. Separate the `casts` group from the `types` group.
2. Reorganize the lints of the `casts` group into their own modules.

Notes:
1. I didn't `fix` #6874 in order to maintain this PR as small as possible.

or-patterns: disallow in `let` bindings

~~Blocked on https://github.com/rust-lang/rust/pull/81869~~

Disallows top-level or-patterns before type ascription. We want to reserve this syntactic space for possible future generalized type ascription.

Fix false positive for unit_arg lint

Fixes #6447

To avoid false positives don't complain about unit args when they come from a path expression, e.g. a local variable.

**Note:** This is my first contribution to Clippy, so I might have messed up somewhere. Any feedback is welcome and I'm happy to work out any kinks.

2f0e9f7d3a or_fun_call: fix suggestion for or_insert(vec![]) 
Applies for `std::collections::hash_map::Entry` and `std::collections::btree_map::Entry`

Example:
Previously, for the following code:
`let _ = hash_map.entry("test".to_owned()).or_insert(vec![]);`
clippy would suggest to use:
`or_insert_with(vec![])`, which causes a compiler error (E0277).

Now clippy suggests:
`or_insert_with(Vec::new)`

ef41f2baf7 Auto merge of #6788 - matthiaskrgr:upper_case_acronyms, r=flip1995 
move upper_case_acronyms back to style, but make the default behaviour less aggressive by default (can be unleashed via config option)

Previous discussion in the bi-weekly clippy meeting for reference: https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Meeting.202021-02-23/near/227458019

Move the `upper_case_acronyms` lint back to the style group.
Only warn on fully-capitalized names by default.
Add add a clippy-config option `upper-case-acronyms-aggressive: true/false` to enabled more aggressive linting on
all substrings that could be capitalized acronyms.

59750dceb8 upper_case_acronyms: add optional aggressive mode and relax default 
Moves the lint back from pedantic to style group.
The lint default now only warns on names that are completely capitalized, like "WORD"
and only if the name is longer than 2 chars (so that names where each of the letter represents a word are still distinguishable).
For example: FP (false positive) would still be "valid" and not warned about (but EOF would warn).

A "upper_case_acronyms_aggressive: true/false" config option was added that restores the original lint behaviour to warn
on any kind of camel case name that had more than one capital letter following another capital letter.
