8284: Reduce memory usage by using global `Arc`-based interning r=jonas-schievink a=jonas-schievink
This saves around 50 mb when running `analysis-stats` on r-a itself. Not a lot, but this infra can be easily reused to intern more stuff.

8285: Don't recheck obligations if we have learned nothing new r=matklad a=flodiebold
This is just the most trivial check: If no inference variables have been updated, and there are no new obligations, we can just skip trying to solve them again. We could be smarter about it, but this already helps quite a bit, and I don't want to touch this too much before we replace the inference table by Chalk's.
Fixes#8263 (well, improves it quite a bit).

8283: Resolve associated types r=flodiebold a=Veykril
Prior we were only resolving paths until the first type was found, then discarding the result if the path wasn't fully consumed. That of course causes associated types to not resolve. Fixes#5003

8274: Adding a few more gifs and screenshots for features in manual r=Veykril a=MozarellaMan
Related #8267,#6539. Gifs are [here](https://github.com/rust-analyzer/rust-analyzer/issues/6539#issuecomment-809574840)
Finishing up the last PR, for the last two features that didn't have a visual example.
For syntax highlighting, I wasn't able to find a theme that displayed the difference between an enum and struct, but I only tried a few apart from the default so there could be one out there!
e.g., with the default light theme, `Ord` and `Ordering` in `use std::cmp::{Ord, Ordering}` had the same highlight colour. So I just went with displaying `mut` items being underlined.

8267: Adding gifs and screenshots for features in manual r=matklad a=MozarellaMan
For #6539
This includes most of gif or screenshot examples of most items in the "Features" header. With the exceptions of:
- **On Typing Assists** - couldn't get it to work for a demo, I'm probably missing something?
- **Structural search and replace** - looked to be already a visual example of the feature
- **Workspace symbol** - wasn't sure how best to show this, all of the examples maybe? Also wasn't sure of the best code example to show it off
- **Semantic Syntax Highlighting** - seemed obvious enough to not need a screenshot, but I could easily add this
All the gifs/pngs are hosted in this [comment](https://github.com/rust-analyzer/rust-analyzer/issues/6539#issuecomment-809574840). Please let me know if any of them aren't suitable (and why) and I'll improve it! Or if you don't like the theme/font

8266: Fix generic arguments being incorrectly offset in qualified trait casts r=flodiebold a=Veykril
We reverse the segments and generic args of the lowered path after building it, this wasn't accounted for when inserting the self parameter in `Type as Trait` segments.

We have a CLI for benchmarking, but no one actually uses it it seems.
Let's try switching to "internal" benchmarks, implemented as rust tests.
They should be easier to "script" to automate tracking of perf
regressions.
8247: internal: ensure that runaway type-inference doesn't block the main loop r=flodiebold a=matklad
We have a bug where type-checking `per_query_memory_usage` takes a
couple of seconds. It also reveals another bug: our type inference is
not cancellable.

8221: Prefer adding `mod` declaration to lib.rs over file.rs in UnlinkedFile fix r=Veykril a=Veykril
When there is a `lib.rs` and `main.rs` in one crate, one usually wants the `lib.rs` file to declare the modules.

8201: Fix recursive macro statements expansion r=edwin0cheng a=edwin0cheng
This PR attempts to properly handle macro statement expansion by implementing the following:
1. Merge macro expanded statements to parent scope statements.
2. Add a new hir `Expr::MacroStmts` for handle tail expression infer.
PS : The scope of macro expanded statements are so strange that it took more time than I thought to understand and implement it :(
Fixes #8171

7907: Autoderef with visibility r=cynecx a=cynecx
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841.
I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below

Fixes#8150.
I implemented a validator that catches this in the tests, but it'd need to get merged in Chalk first.
