Don't allow `DESTDIR` to influence LLVM builds
When running a command like `DESTDIR=foo x.py install` in a completely
clean build directory, this will cause LLVM to be installed into
`DESTDIR`, which then causes the build to fail later when it attempts
to *use* those LLVM files.
This commit re-uses the `transparent_newtype_field` function instead of
manually calling `is_zst` on normalized fields to determine which field
in a transparent type is the non-zero-sized field, thus avoiding an ICE.

When encountering a unit or tuple pattern for a struct-like item, suggest
using the correct pattern.
Use `insert_field_names_local` when evaluating variants and store field
names even when the list is empty in order to produce accurate
structured suggestions.
improve advice in iter_nth_zero
fixes#5783
*Please keep the line below*
changelog: For iter_nth_zero, the "use .next()" replacement advice is on the last line of the code snippet, where it is vulnerable to truncation. Display that advice at the beginning instead.
Reprise: new lint: Unintentional return of unit from closures expecting Ord
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.
Fixes#5080
Reprise of #5348 where I addressed all the comments there
changelog: add lint [`unit_return_expecting_ord`]
This commit replaces the use of `expect_local` and `hir().get` to fetch
the identifier for a ADT with `item_name` - which works across crates.

Update Clippy
~~I'm not sure, if we can/should land this before beta is branched.~~ (Nvm, beta is already branched) The last Clippy update was 3 weeks ago: #73660
This includes, besides other minor things:
- New lints
- One lint deprecation
- One lint was moved to pedantic
- Some FP fixes
- I think an ICE fix?
cc @Mark-Simulacrum

We probably should also think of some process when and how often we should sync Clippy to the rust repo, so that we don't end up with those huge updates. Maybe every 2 weeks? Or even every week? cc @rust-lang/clippy
Remove unnecessary type hints from Wake internals
While working on https://github.com/rust-lang/rust/pull/74304 I noticed we were writing out the type signature twice in some internal `Wake` impl methods; this streamlines that. Thanks!
Clarify the description for rfind
Changes the wording in rfind description to be clearer and the example code to illustrate the difference between
find and rfind
typeck: report placeholder type error w/out span
Fixes#74086.
This PR fixes a regression introduced in rust-lang/rust#70369 which meant that an error was not being emitted for invalid placeholder types when there wasn't a span available.

add (unchecked) indexing methods to raw (and NonNull) slices
This complements the existing (unstable) `len` method. Unfortunately, for non-null slices, we cannot call this method `as_ptr` as that overlaps with the existing method of the same name.
If this looks reasonable to accept, I propose to reuse the https://github.com/rust-lang/rust/issues/71146 tracking issue and rename the feature get to `slice_ptr_methods` or so.

typeck: check for infer before type impls trait
Fixes#73886.
This PR checks that the target type of the cast (an error related to which is being reported) does not have types to be inferred before checking if it implements the `From` trait.

Obviate #[allow(improper_ctypes_definitions)]
Modifies the return type for `fn entry` so that allowing
improper_ctypes_definitions is no longer necessary. This change is
derived from a similar pattern in `libstd/sys/sgx/abi/usercalls/raw.rs`
with `UsercallReturn`.

Rename collapsable_if fix suggestion to "collapse nested if block"
The name "try" is confusing when shown as quick fix by rust-analyzer
changelog: Rename `collapsable_if` fix suggestion to "collapse nested if block"
Use step_unchecked more liberally in range iter impls
Without these `_unchecked`, these operations on iterators of `char` fail to optimize out the unreachable panicking condition on overflow.
