21b68a328c Remove module_lang_items 
It isn't used anywhere except in `crate_lang_items`. Remove it to
slightly reduce memory usage and simplify the code.

28b5334580 Avoid querying attributes in item tree lowering 
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.

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`.

6834: Use Attrs::docs in runnables instead of DocCommentsOwner r=kjeremy a=Veykril

I figured that we should probably move as much of the doc usage to the HIR as possible hence this PR. If we should keep this AST-based feel free to close.

This change does have the nice(but not really useful as I doubt anyones gonna write doc tests like these) side effect that these two doc string snippets allow being run now.

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
