6946: Better fuzzy heuristics r=matklad a=SomeoneToIgnore
Continuation of the https://github.com/rust-analyzer/rust-analyzer/pull/6922, mainly created for a test.
Turns out our current completions tests were sorting the completions by label, I had to remove that to test the order properly and update this order in a bunch of tests (ergo the changes)

6948: Add API for mapping `Attr` back to its syntax node r=jonas-schievink a=jonas-schievink
This will be useful for emitting diagnostics pertaining to a specific attribute

Curiously, LSP uses different enums for those, and unsurprising and
annoyingly, there are things which exist in one but not in the other.
Let's not repeat the mistake and unify the two things
6901: Temp fixes panic caused by no ast for proc-macro r=maklad a=edwin0cheng
There are some panic when hover/goto definition for proc-macro. It is because in current design, we don't have `ast-node` for proc-macro and then it trigger [this](479d1f7eec/crates/hir/src/has_source.rs (L116)) line to panic.
This PR is a temp fix for all of these similar to bd4c352831/crates/completion/src/render/macro_.rs (L42)

6912: Default to host platform for cargo metadata r=jonhoo a=jonhoo
This modifies the logic for calling cargo metadata so that it will use
the host platform if no explicit target platform is given. This is
needed since cargo metadata defaults to outputting information for _all_
targets.
Fixes#6908.

We used to have `Def` suffix for all symbols, but we moved off from
that. `FunctionDef` isn't better than `Function`. Looks like we've
forgot to change `Impl` though!
6907: Lifetime reference search r=matklad a=Veykril
PR #6787 but rewritten to make use of the HIR now. This only applies to Lifetimes, not labels. Also Higher-Ranked Trait Bounds aren't supported yet, but I feel like this PR is big enough as is which is why I left them out after noticing I forgot about them.
Supporting renaming required slight changes in the renaming module as lifetime names aren't allowed for anything but lifetimes(and labels) and vice versa for normal names.

ItemTree is per-file, so there is no unique crate associated with it.
This means that it cannot know the active CfgOptions and thus couldn't
handle `cfg_attr`.
Prepare it for `cfg_attr`s by avoiding accessing attributes.

6889: Resolve `macro-error` diagnostics on asm & llvm_asm r=matklad a=lf-
We currently stub these out as returning unit.
This fixes spurious RA `macro-error` diagnostics introduced somewhere around 0.2.400 in the following:
```rust
unsafe { asm!(""); llvm_asm!(""); }
```
I'd ideally like to write a unit test for this, but I'm not familiar with where the tests for `hir_expand` are.
Thanks to @edwin0cheng for help on resolving this issue.

6862: Add LifetimeParam resolving to Semantics r=matklad a=Veykril
This is stuff required for the lifetime references/definitions PR. I pulled this out to make it easier to review as well as because there is one thing that still has to be addressed which can be found in the review comments.

Since we just tried running `rustup component add`, it doesn't make sense to me
to recommend trying that again. If we're reaching this case, it's probably more
likely that rustc was installed via package manager, in which case the source
should be installed the same way (e.g. if you install the rust-src package on
Ubuntu it will install a symlink in the right place to make our sysroot
detection work).
6852: Ignore lifetime params in substitutions r=matklad a=Veykril
[`hir_ty::utils::Generics`](https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/hir_ty/src/utils.rs#L153) currently only assumes type parameters but not lifetime parameters and therefor creates incorrect index and length calculations, this PR just makes the use sites ignore LifetimeGenerics for now.
This fixes the panic at least locally for me for `analysis-stats`. Funnily enough this panic prevented me from using reference search for the `args` field to fix this problem.

6818: Add Lifetimes to the HIR r=matklad a=Veykril
This doesn't handle resolve yet as I don't know yet how that will be used. I'll get to that once I start moving the lifetime reference PR to the hir.
This also adds a new `hir` name type for lifetimes and labels, `hir::LifetimeName`.

The test should cover all the interesting cases I believe(main part of it is copied from the loop label break test above it).
The test is indented to stay consistent with the rest of the tests in the file, I can dedent all the tests in the file in a follow up PR if desired.

derive(Clone, Copy) reads better than derive(Copy, Clone).
However, we preserve the reverse ordering in the lookup text for
sorting purposes. That way, it's convenient to type just `Ord` to
derive everything.
6807: Replicate Cargo environment variables r=jonas-schievink a=jonas-schievink
These might be relied on by procedural macros, and can also be accessed via `env!`.

6771: Properly attach inner attributes in Attrs::new r=matklad a=Veykril
Properly attach inner and outer attributes to the things they actually belong to in the HIR. ~~I can add some tests for this if wanted once I know where to put them/how to test for this.~~ Put some tests into `hover.rs`.
So the following snippet
```rust
mod foo {
//! Hello
}
```
now shows `Hello` on hover 🎉Fixes#2148

6761: Make config.rs a single source of truth for configuration. r=matklad a=matklad
Configuration is editor-independent. For this reason, we pick
JSON-schema as the repr of the source of truth. We do specify it using
rust-macros and some quick&dirty hackery though.
The idea for syncing truth with package.json is to just do that
manually, but there's a test to check that they are actually synced.
I'll add something like `rust-analyzer --config-schema` in a follow-up
commit.

There's CLI to print config's json schema:
$ rust-analyzer --print-config-schema
We go with a CLI rather than LSP request/response to make it easier to
incorporate the thing into extension's static config. This is roughtly
how we put the thing in package.json.
6750: Remove documentation query, move doc handling to attributes r=matklad a=Veykril
Fixes#3182
Removes the documentation query in favor of `Attrs::docs`. Attrs already handlded doc comments partially but the alloc saving check was wrong so it only worked when other attributes existed as well. Unfortunately the `new` constructor has to do an intermediate allocation now because we need to keep the order of mixed doc attributes and doc comments.
I've also partially adjusted the `hover` module to have its tests check the changes, it still has some `HasSource` trait usage due to the `ShortLabel` trait usage, as that is only implemented on the Ast parts and not the Hir, should this ideally be implemented for the Hir types as well?(would be a follow up PR of course)

Fixes#6742.
Doc attributes should be concatenated via a single linebreak as written in the [rustdoc book](https://doc.rust-lang.org/nightly/rustdoc/the-doc-attribute.html).
Also changed the loop to use an iterator to get rid of the `docs.trim_end_matches("\n\n").to_owned()` part using `Itertools::intersperse`.

6731: Add replace_match_with_if_let assist r=matklad a=Veykril
Basically the counterpart to `replace_if_let_with_match`, I personally sometimes want to replace matches like
```rust
match foo {
pat => expr,
_ => (),
}
```
into the corresponding
```rust
if let pat = foo {
expr
}
```
which is the main reasoning behind this.
I put this into the same file as `replace_if_let_with_match` because the are complementing each other and I would probably rename the file to something like `replace_if_let_match` but I didn't do that for now because I was unsure whether git would still view this as a rename or not due to the amount of changes in the file so that the diff is still properly visible for now.

6733: Update attributes completion list r=jonas-schievink a=Veykril
Might be nice to have them grouped for readability/maintainability similar to how the [reference](https://doc.rust-lang.org/reference/attributes.html#built-in-attributes-index) does it but that would require the use of a `OnceCell` for sorting the entries back after construction.

Without arbitrary self types, the self type could never refer to the method type
parameters, so this wasn't a problem; but with arbitrary self types, it can.
This fixes the crash from #6668; but it doesn't make method resolution work for
these methods.

Previously it attached them to the result of the macro expansion (or, if no result was produced, to the file containing the invocation). Always use the file containing the invocation.
This doesn't seem to have any observable difference, but seems better in theory.
