3778: Use more functional programming in ArenaMap::insert r=matklad a=kjeremy
I find this more readable and it flattens out the body a little. Others may disagree.

3781: Add crate versions when running cargo -p commands. r=matklad a=o0Ignition0o
If someone (unfortunately) creates a project that happens to have the same name as one of its (future) dependencies, there is [a way for them to change the dependency's alias in the Cargo.toml file](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#renaming-dependencies-in-cargotoml), to mitigate the name conflict. Unfortunately cargo -p commands don't seem to pick it up, which seems to put rust-analyzer run commands in a tough situation:
```
> Executing task: cargo test --package config --example default -- tests --nocapture <
error: There are multiple `config` packages in your project, and the specification `config` is ambiguous.
Please re-run this command with `-p <spec>` where `<spec>` is one of the following:
config:0.1.0
config:0.9.3
The terminal process terminated with exit code: 101
```
cargo suggests us to be more specific and refer to a package by its name and version, which this PR achieves.
I passed the version as a String because I don't really understand how the ra_db types work, but I would love to switch it to [a fully fledged Version type](https://steveklabnik.github.io/semver/semver/index.html) if you guide me towards that :)

Until now cargo commands with the -p flag would pass the package name only.
It doesn't play super well with the toml Renaming dependencies feature.
This commit specifies the package name and version when a cargo command is run with the -p flag,
to avoid ambiguities.
This commit changes the parser to attach doc-comments to the corresponding declaration in case there are newlines in between the doc-comment and the declaration.
3761: Append new match arms rather than replacing all of them r=matklad a=mattyhall
This means we now retain comments when filling in match arms. This fixes#3687. This is my first contribution so apologies if it needs a rethink! I think in particular the way I find the position to append to and remove_if_only_whitespace are a little hairy.
