4489: Memory allocation optimization r=matklad a=simonvandel
I did some profiling using DHAT, and this was what I could easily optimize without much knowledge of the codebase.
This speeds up analysis-stats on rust-analyser by ~4% on my local machine.

4484: Allow calling dyn trait super trait methods without the super trait in scope r=flodiebold a=flodiebold
This also removes some vestiges of the old impl trait support which I think aren't currently in use.

4479: Chalk upgrade r=matklad a=flodiebold
This includes the fix for `dyn Trait` super traits, but I noticed that still a lot of `db.super_trait_method()` calls don't work because the super trait isn't in scope (because it doesn't actually need to be). Somehow, I thought we handled that already, but I'll fix it in a separate PR. Also I'll see what happens if we use more of Chalk's new built-in types and traits in a separate PR.

4288: Add rename self to parameter and back. r=zbsz a=zbsz
This is a first stab at #3439
I liked the idea to do this as a rename instead of separate assist, so I tried implementing that.
It mostly works, but I'm sure there are some cases that I missed, especially in regards to parameter type.
Note: I'm playing with this this as a way to learn Rust and this project. So I'm sure it could be cleaner and put in better places`. Any suggestions?

4470: Handle `Self` in values and patterns r=matklad a=flodiebold
I.e.
- `Self(x)` or `Self` in tuple/unit struct impls
- `Self::Variant(x)` or `Self::Variant` in enum impls
- the same in patterns
Fixes#4454.

4448: Generate configuration for launch.json r=vsrs a=vsrs
This PR adds two new commands: `"rust-analyzer.debug"` and `"rust-analyzer.newDebugConfig"`. The former is a supplement to the existing `"rust-analyzer.run"` command and works the same way: asks for a runnable and starts new debug session. The latter allows adding a new configuration to **launch.json** (or to update an existing one).
If the new option `"rust-analyzer.debug.useLaunchJson"` is set to true then `"rust-analyzer.debug"` and Debug Lens will first look for existing debug configuration in **launch.json**. That is, it has become possible to specify startup arguments, env variables, etc.
`"rust-analyzer.debug.useLaunchJson"` is false by default, but it might be worth making true the default value. Personally I prefer true, but I'm not sure if it is good for all value.
----
I think that this PR also solves https://github.com/rust-analyzer/rust-analyzer/issues/3441.
Both methods to update launch.json mentioned in the issue do not work:
1. Menu. It is only possible to add a launch.json configuration template via a debug adapter. And anyway it's only a template and it is impossible to specify arguments from an extension.
2. DebugConfigurationProvider. The exact opposite situation: it is possible to specify all debug session settings, but it is impossible to export these settings to launch.json.
Separate `"rust-analyzer.newDebugConfig"` command looks better for me.

4445: Correctly fill default type parameters r=flodiebold a=montekki
Fixes#3877
So, basically even if the parameters are omitted from the `impl` block, check the parameters in `trait` if they have a default type, and if they do go from `hir` to `ast::TypeArg`. I've added a helper for that but I am not sure that it's a proper way to go from `hir` to `ast` here.

4405: Make some stuff public so that they can be reused by other tools r=pksunkara a=pksunkara
So, my little experiment of building a code analysis tool using rust-analyzer is successful. I am going to proceed to build the tool now. This PR makes the needed things public.
I know there were some things about trying to change stuff regarding loading workspaces, which would make it more easier for other tools to reuse. But, until then, it should be okay using this `load_cargo` fn.
Btw, if I were publish my tool, I would need the `ra` crates to be released. Since @matklad told me that he doesn't want to care about breaking stuff, I would propose the following.
Every monday, during the weekly release, we release a new pre v1 minor version of all the crates. That way, we don't need to care about breaking stuff but still have rust-analyzer on crates.io.
I made https://github.com/pksunkara/cargo-workspaces to help release workspace crates easily.
So, coming week, we start with `0.1.0`, then week after that, we release `0.2.0` and then `0.3.0` etc.. until we decide on `1.0.0` which is probably when the compiler team also starts using the crates. There is no limit to the minor versions (we can even have `0.150.0` or `0.1500.0`), so I don't see anything wrong with this strategy.
