Tweak suggestion for missing field in patterns
Account for parser recovered struct and tuple patterns to avoid invalid
suggestion.
Follow up to #81103.
Improve URLs handling
Fixes#81330.
Explanations: before this PR, when emptying the search input, we still had `?search=` in the URL, which wasn't very nice. Now, if the search is empty, we drop the `?search=` part.
Also, I realized while working on this PR that when we clicked on a menu link when we were on the search results, the search parameters would look like: `?search=#the-anchor`, which was super weird. Now, it looks like this: `?search=the-search#the-anchor`.
Also, I didn't use the `Url` very nice API because it's not available in any IE version (sadness...).

Make `-Z time-passes` less noisy
- Add the module name to `pre_AST_expansion_passes` and don't make it a
verbose event (since it normally doesn't take very long, and it's
emitted many times)
- Don't make the following rustdoc events verbose; they're emitted many times.
+ build_extern_trait_impl
+ build_local_trait_impl
+ build_primitive_trait_impl
+ get_auto_trait_impls
+ get_blanket_trait_impls
- Remove the `get_auto_trait_and_blanket_synthetic_impls` rustdoc event; it's wholly
covered by get_{auto,blanket}_trait_impls and not very useful.
I found this while working on https://github.com/rust-lang/rust/pull/81275 but it's independent of those changes.
Make more traits of the From/Into family diagnostic items
Following traits are now diagnostic items:
- `From` (unchanged)
- `Into`
- `TryFrom`
- `TryInto`
This also adds symbols for those items:
- `into_trait`
- `try_from_trait`
- `try_into_trait`

Print failure message on all tests that should panic, but don't
Fixes#80861. Tests with the `#[should_panic]` attribute should always print a failure message if no panic occurs, regardless of whether or not an `expected` panic message is specified.
Refractor a few more types to `rustc_type_ir`
In the continuation of #79169, ~~blocked on that PR~~.
This PR:
- moves `IntVarValue`, `FloatVarValue`, `InferTy` (and friends) and `Variance`
- creates the `IntTy`, `UintTy` and `FloatTy` enums in `rustc_type_ir`, based on their `ast` and `chalk_ir` equilavents, and uses them for types in the rest of the compiler.
~~I will split up that commit to make this easier to review and to have a better commit history.~~
EDIT: done, I split the PR in commits of 200-ish lines each

Stabilize `Seek::stream_position` (feature `seek_convenience`)
Tracking issue: #59359
Unresolved questions from tracking issue:
- "Override `stream_len` for `File`?" → we can do that in the future, this does not block stabilization.
- "Rename to `len` and `position`?" → as noted in the tracking issue, both of these shorter names have problems (`len` is usually a cheap getter, `position` clashes with `Cursor`). I do think the current names are perfectly fine.
- "Rename `stream_position` to `tell`?" → as mentioned in [the comment bringing this up](https://github.com/rust-lang/rust/issues/59359#issuecomment-559541545), `stream_position` is more descriptive. I don't think `tell` would be a good name.
What remains to decide, is whether or not adding these methods is worth it.
Check for rmeta crates when getting existing crates from cache
This change makes sure to check for rmeta files when resolving crates instead of always going to disk in that case.
Trying to shrink_to greater than capacity should be no-op
Per the discussion in https://github.com/rust-lang/rust/issues/56431, `shrink_to` shouldn't panic if you try to make a vector shrink to a capacity greater than its current capacity.
Remove CACHE_KEY global
We realized in https://github.com/rust-lang/rust/pull/80914 that the cache handling (through a global) needed to be updated to make it much easier to handle.

Make weak item traversal deterministic
Fix#81296.
(No test added. The relevant test *is* ui/panic-handler/weak-lang-item.rs, and this change should make it less flaky.)
Refine "remove semicolon" suggestion in trait selection
Don't suggest it if the last statement doesn't have a semicolon
Fixes#81098
See also #54771 for why this suggestion was added
tidy: Some code cleanup.
This is just some cleanup that shouldn't have any change in behavior. (See commit messages for more details.)
* Remove cargo check. This test wasn't working, and is no longer valid.
* Remove edition filter exceptions. They are no longer necessary.
* Remove unnecessary trailing semicolon. Otherwise the warning will prevent tidy from building after the beta branch.

rustdoc: Document CommonMark extensions.
This updates the rustdoc book to include some documentation on the CommonMark extensions that rustdoc supports.
rustc_codegen_ssa: use wall time for codegen_to_LLVM_IR time-passes entry
Use elapsed wall time spent on codegen_to_LLVM_IR for all CGUs as a
whole, rather than the sum for each CGU (the distinction matters for
parallel builds, where some CGUs are processed in parallel).
Fix some bugs reported by eslint
Simply went into `src/librustdoc/html/static/` and ran `eslint *.js` in case you want to reproduce. :)

BTreeMap: test all borrowing interfaces and test more chaotic order behavior
Inspired by #81169, test what happens if you mess up order of the type with which you search (as opposed to the key type).
r? `@Mark-Simulacrum`
Add `unwrap_unchecked()` methods for `Option` and `Result`
In particular:
- `unwrap_unchecked()` for `Option`.
- `unwrap_unchecked()` and `unwrap_err_unchecked()` for `Result`.
These complement other `*_unchecked()` methods in `core` etc.
Currently there are a couple of places it may be used inside rustc (`LinkedList`, `BTree`). It is also easy to find other repositories with similar functionality.
Fixes#48278.
BTreeMap: bring back the key slice for immutable lookup
Pave the way for binary search, by reverting a bit of #73971, which banned `keys` for misbehaving while it was defined for every `BorrowType`. Adding some `debug_assert`s along the way.
