Minor fix and addition to doc comments
1. Fixed doc comment of struct 'rustc_middle::mir::Location'
Currently, the general explanation of the struct appears at the field
explanation section. I moved and changed the doc comments slightly, so
that the general explanation would appear in the proper location in
docs.
2. Added doc comment explaining 'rustc_mir::util::pretty::write_mir_fn'
Unlike other counterparts, brief explanation for this function was missing,
so I added one.
Thank you for reviewing this PR :)
Implement `Clone` for `liballoc::collections::linked_list::Cursor`.
This implements `Clone` for linked list `Cursor`. Implementing `Copy` is also possible here, but i'm not sure whether i should also do it.

Use query to determine whether function needs const checking
Resolves#69615.
The HIR const-checker was checking the `constness` of a function's `fn_sig` to determine whether a function needed const-checking. Now that const trait impls are a thing, this is no longer enough. All code should use the `is_const_fn_raw` query instead, which takes the constness of the impl block into account.

Add `ConstKind::Error` and convert `ErrorHandled::Reported` to it.
By replicating the `ty::Error` approach to encoding "an error has occurred", all of the mechanisms that skip redundant/downstream errors are engaged and help out (see the reduction in test output).
This PR also adds `ErrorHandled::Linted` for the lint case because using `ErrorHandled::Reported` *without* having emitted an error that is *guaranteed* to stop compilation, is incorrect now.

Fix typo in Default trait docs: Provides -> Provide
An earlier commit (99ed06e) accidentally changed this paragraph from the original, imperative `Provide` to the present tense `Provides`. The latter is indeed the standard for Rustdoc comments relating to a function or method, but this snippet is introducing the `Default` trait in general terms and not talking about any particular function. I believe this change was likely made in error and should be reverted.
Dogfood or_patterns in the standard library
We can start using `or_patterns` in the standard library as a step toward stabilization.

reword Miri validity errors: undefined -> uninitialized
I don't think we say "undefined value" or anything like that anywhere in the docs or so, but we do use the term "uninitialized memory", so I think we should do the same here.
Longer-term, I think we should also internally rename "undef" to "uninit".

Hides default fns inside Fuse impl to avoid exposing it to any crate
Fixes#70796
@cuviper I've added some default, private traits to do the job for us. If required, I can expose them to a specific visibility if you want to call these functions for #70332

Generalizes code from PR #67020, which handled case when imports change.

Minor fixes to doc comments of 'VecDeque'
1. Changed descriptions of `fn get` & `fn get_mut`.
Since both of these functions are returning references, and not the owned value, I thought the doc comments could be fixed to be consistent with doc comments of `fn front` & `fn front_mut`.
2. Other changes are minor fixes or additions for clarification.
Thank you for taking a look :)

- Don't use debug display for error object. (rust-lang/cargo#8119)
- Add backwards-compatibility for old cargo-tree flags. (rust-lang/cargo#8115)
- Try to avoid panics on buggy (?) clocks (rust-lang/cargo#8114)
Don't use the HirId to NodeId map in MIR
Another step towards not having to build a `HirId` to `NodeId` map other than for doc and RLS purposes.
We are currently sorting `unsafe` blocks by `NodeId` in `check_unsafety`; change it to sorting by `Span` instead; this passes the tests, but better ideas are welcome.
In addition, simplify the split between the used and unused `unsafe` blocks for readability and less sorting.
