6964: Add full pattern completions for Struct and Variant patterns r=matklad a=Veykril
Just gonna call it full pattern completion as pattern completion is already implemented in a sense by showing idents in pattern position. What this does is basically complete struct and variant patterns where applicable(function params, let statements and refutable pattern locations).
This does not replace just completing the corresponding idents of the structs and variants, instead two completions are shown for these, a completion for the ident itself and a completion for the pattern(if the pattern make sense to be used that is). I figured in some cases one would rather type out the pattern manually if it has a lot of fields but you only care about one since this completion would cause one more work in the end since you would have to delete all the extra matched fields again.
These completions are tagged as `CompletionKind::Snippet`, not sure if that is the right one here.

* simplify code
* correctly handle crate roots and mod.rs files (nested inline modules
are still mishandled)
* make sure that new text contains a trailing newline
6993: Clean up descriptions for settings r=matklad a=rherrmann
Use two consecutive newlines (`\n\n`) to actually continue text on a
new line.
Use proper markup to reference related settings.
Consistently format references to files, command line arguments, etc.
as `code`. Format mentions of UI elements in _italic_.
Fix typos, add missing full-stops, add missing default values.

6982: Remove parentheses when inverting `!(cond)` r=matklad a=Jesse-Bakker
Followup to #6894
When inverting a composite condition twice, the parentheses were left. This also removes those unnecessary parentheses when applying the invert-if assist.

6921: Higher-ranked trait bounds for where clauses r=flodiebold a=Veykril
There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to. I wasn't entirely sure what I could do about this but given nothing really uses lifetimes like that currently I figured it might be fine? Open to suggestions for that problem.

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.

6897: Basic support for macros 2.0 r=jonas-schievink a=jonas-schievink
This adds support for (built-in-only) macros 2.0, and removes some hacks used for builtin derives, which are declared via macros 2.0 in libcore.
First steps for https://github.com/rust-analyzer/rust-analyzer/issues/2248.
Blocked on https://github.com/rust-analyzer/ungrammar/pull/16.

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`.

6839: Infer labeled blocks r=flodiebold a=Veykril
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.
