Correctly handle links starting with whitespace
Part of https://github.com/rust-lang/rust/issues/107995.
I just got this issue, wrote a fix and then saw the issue. So here's the PR. ^^'

Implement partial support for non-lifetime binders
This implements support for non-lifetime binders. It's pretty useless currently, but I wanted to put this up so the implementation can be discussed.
Specifically, this piggybacks off of the late-bound lifetime collection code in `rustc_hir_typeck::collect::lifetimes`. This seems like a necessary step given the fact we don't resolve late-bound regions until this point, and binders are sometimes merged.
Q: I'm not sure if I should go along this route, or try to modify the earlier nameres code to compute the right bound var indices for type and const binders eagerly... If so, I'll need to rename all these queries to something more appropriate (I've done this for `resolve_lifetime::Region` -> `resolve_lifetime::ResolvedArg`)

Avoid accessing HIR when it can be avoided
Experiment to see if it helps some incremental cases.
Will be rebased once https://github.com/rust-lang/rust/pull/107942 gets merged.

Resolve documentation links in rustc and store the results in metadata
This PR implements MCP https://github.com/rust-lang/compiler-team/issues/584.
Doc links are now resolved in rustc and stored into metadata, so rustdoc simply retrieves them through a query (local or extern),
Code that is no longer used is removed, and some code that no longer needs to be public is privatized.
The removed code includes resolver cloning, so this PR fixes https://github.com/rust-lang/rust/issues/83761.

Revert "Make PROC_MACRO_DERIVE_RESOLUTION_FALLBACK a hard error"
This reverts commit 7d82cadd97 aka PR #84022
I am doing this to buy us some time with respect to issue #106337 w.r.t. the 1.67 release.
Use UnordMap and UnordSet for id collections (DefIdMap, LocalDefIdMap, etc)
This PR changes the `rustc_data_structures::define_id_collections!` macro to use `UnordMap` and `UnordSet` instead of `FxHashMap` and `FxHashSet`. This should account for a large portion of hash-maps being used in places where they can cause trouble.
The changes required are moderate but non-zero:
- In some places the collections are extracted into sorted vecs.
- There are a few instances where for-loops have been changed to extends.
~~Let's see what the performance impact is. With a bit more refactoring, we might be able to get rid of some of the additional sorting -- but the change set is already big enough. Unless there's a performance impact, I'd like to do further changes in subsequent PRs.~~
Performance does not seem to be negatively affected ([perf-run here](https://github.com/rust-lang/rust/pull/106977#issuecomment-1396776699)).

Fix bad import suggestion with nested `use` tree
Fixes#105566Fixes#105373
Ideally, we'd find some way to turn these into structured suggestions -- perhaps on a separate line as a different `use` statement, but I have no idea how to access the span for the whole `use` from this point in the import resolution code.
Point out span where we could introduce higher-ranked lifetime
Somewhat addresses #105422, but not really. We don't have that much useful information here since we're still in resolution :^(
Maybe this suggestion isn't worth it. If the reviewer has an idea how we can get a more succinct binder information for a structured suggestion, it would be appreciated.
add function to tell the identical errors for ambiguity_errors
if 2 errors of the kind and ident and span of the ident, b1, b2 and misc1 misc2 are the same we call these 2 ambiguity errors identical
prevent identical ambiguity error from pushing into vector of ambiguity_errors this will fix#105177
if 2 errors of the kind and ident and span of the ident, b1, b2 and misc1 misc2 are the same
then these 2 ambiguity errors matched
prevent identical ambiguity error from pushing into vector of ambiguity_errors
this will fix#105177
Lower them into a single item with multiple resolutions instead.
This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
make simple check of prinf function
Fixes https://github.com/rust-lang/rust/issues/92898
With this commit we start to make some simple
check when the name resolution fails, and
we generate some helper messages in case the
name is a C name like in the case of the `printf`
and suggest the correct rust method.

Prefer doc comments over `//`-comments in compiler
Doc comments are generally nicer: they show up in the documentation, they are shown in IDEs when you hover other mentions of items, etc. Thus it makes sense to use them instead of `//`-comments.
Separate lifetime ident from lifetime resolution in HIR
Drive-by: change how suggested generic args are computed.

I recommend reviewing commit-by-commit.
