5327: Mark fixes from check as preferred r=matklad a=kjeremy

This allows us to run the auto fix command from vscode to automatically fix diagnostics in the file.

They are also distinguished in the UI.

Merge #5350 
5350: Filter assists r=matklad a=kjeremy

Uses the `CodeActionContext::only` field to compute only those assists the client cares about.

It works but I don't really like the implementation.

Merge #5354 
5354: Add opt-in mimalloc feature r=matklad a=ivan

This adds a `mimalloc` feature to use [mimalloc](https://github.com/microsoft/mimalloc) via [mimalloc_rust](https://github.com/purpleprotocol/mimalloc_rust), and a corresponding `cargo xtask install --server --mimalloc`.

In my tests on Linux, mimalloc seems to run consistently faster than jemalloc and uses only slightly more memory in `analysis-stats` on chalk. Also, builds with mimalloc produce a binary 3MB smaller than builds with jemalloc.

A summary of `env time -v cargo run --release -p rust-analyzer -- analysis-stats ../chalk/` runs on NixOS master on an Intel 4790K in VMware Workstation:

<table>
<tr>
<td></td><td>self-reported time</td><td>elapsed time</td><td>max RSS</td>
</tr>
<tr><td>glibc 2.30 run 1</td><td>225.1 sec</td><td>3:46.91</td><td>1075208</td></tr>
<tr><td>glibc 2.30 run 2</td><td>228.4 sec</td><td>3:50.13</td><td>1074996</td></tr>
<tr><td>jemalloc run 1</td><td>201.8 sec</td><td>3:23.03</td><td>1055960</td></tr>
<tr><td>jemalloc run 2</td><td>199.2 sec</td><td>3:20.41</td><td>1065040</td></tr>
<tr><td>mimalloc run 1</td><td>188.6 sec</td><td>3:09.77</td><td>1105584</td></tr>
<tr><td>mimalloc run 2</td><td>185.0 sec</td><td>3:06.23</td><td>1108132</td></tr>
<tr><td>mimalloc + lto run 1</td><td>160.7 sec</td><td>2:41.80</td><td>1106076</td></tr>
<tr><td>mimalloc + lto run 2</td><td>162.2 sec</td><td>2:43.31</td><td>1104268</td></tr>
</tr>
</table>

I included an `lto = true; codegen-units = 1` run out of curiosity, this PR doesn't enable it.

5244: Add a command to compute memory usage statistics r=matklad a=jonas-schievink

This allows inspecting memory usage on a live rust-analyzer instance after it has been used interactively.

This will only work with `--features jemalloc`, so maybe it should print something more useful when that's not available? Right now it will just print 0 Bytes for every query.

5101: Add expect -- a light-weight alternative to insta r=matklad a=matklad

This PR implements a small snapshot-testing library. Snapshot updating is done by setting an env var, or by using editor feature (which runs  a test with env-var set). 

Here's workflow for updating a failing test:

![expect](https://user-images.githubusercontent.com/1711539/85926956-28afa080-b8a3-11ea-9260-c6d0d8914d0b.gif)

Here's workflow for adding a new test:

![expect-fresh](https://user-images.githubusercontent.com/1711539/85926961-306f4500-b8a3-11ea-9369-f2373e327a3f.gif)

Note that colorized diffs are not implemented in this PR, but should be easy to add (we already use them in test_utils). 

Main differences from insta (which is essential for rust-analyzer development, thanks @mitsuhiko!):
* self-updating tests, no need for a separate tool
* fewer features (only inline snapshots, no redactions)
* fewer deps (no yaml, no persistence)
* tighter integration with editor
* first-class snapshot object, which can be used to write test functions (as opposed to testing macros)
* trivial to tweak for rust-analyzer needs, by virtue of being a workspace member. 

I think eventually we should converge to a single snapshot testing library, but I am not sure that `expect` is exactly right, so I suggest rolling with both insta and expect for some time (if folks agree that expect might be better in the first place!). 

# Editor Integration Implementation 

The thing I am most excited about is the ability to update a specific snapshot from the editor. I want this to be available to other snapshot-testing libraries (cc @mitsuhiko, @aaronabramov), so I want to document how this works. 

The ideal UI here would be a code action (💡). Unfortunately, it seems like it is impossible to implement without some kind of persistence (if you save test failures into some kind of a database, like insta does, than you can read the database from the editor plugin). Note that it is possible to highlight error by outputing error message in rustc's format. Unfortunately, one can't use the same trick to implement a quick fix. 

For this reason, expect makes use of another rust-analyzer feature -- ability to run a single test at the cursor position. This does need some expect-specific code in rust-analyzer unfortunately. Specifically, if rust-analyzer notices that the cursor is on `expect!` macro, it adds a special flag to runnable's JSON. However, given #5017 it is possible to approximate this well-enough without rust-analyzer integration. Specifically, an extension can register a special runner which checks (using regexes) if rust-anlyzer runnable covers text with specific macro invocation and do special magic in that case. 

closes #3835

874a5f80c7 Scale progress down 
There are two reasons why we don't want a generic ra_progress crate
just yet:

*First*, it introduces a common interface between separate components,
and that is usually undesirable (b/c components start to fit the
interface, rather than doing what makes most sense for each particular
component).

*Second*, it introduces a separate async channel for progress, which
makes it harder to correlate progress reports with the work done. Ie,
when we see 100% progress, it's not blindly obvious that the work has
actually finished, we might have some pending messages still.

4937: Allow overriding rust-analyzer display version r=matklad a=oxalica

The build script invokes `git` for version information which is displayed when rust-analyzer is called with `--version`. But in build environment without `git` or when the source code is not a git repo, there's no way to manually specify the version information.

This patch respects environment variable ~`REV`~ `RUST_ANALYZER_REV` in compile time for overriding.

The language server protocol includes a semantic modifier for documentation. This change exports that modifier for doc comments so users can choose to highlight them differently compared to regular comments.

4913: Remove debugging code for incremental sync r=matklad a=lnicola



4915: Inspect markdown code fences to determine whether to apply syntax highlighting r=matklad a=ltentrup

Fixes #4904 

4916: Warnings as hint or info r=matklad a=GabbeV

Fixes #4229 

This PR is my second attempt at providing a solution to the above issue. My last PR(#4721) had to be rolled back(#4862) due to it overriding behavior many users expected. This PR solves a broader problem while trying to minimize surprises for the users. 

### Problem description
The underlying problem this PR tries to solve is the mismatch between [Rustc lint levels](https://doc.rust-lang.org/rustc/lints/levels.html) and [LSP diagnostic severity](https://microsoft.github.io/language-server-protocol/specification#diagnostic). Rustc currently doesn't have a lint level less severe than warning forcing the user to disable warnings if they think they get to noisy. LSP however provides two severitys below warning, information and hint. This allows editors like VSCode to provide more fine grained control over how prominently to show different diagnostics.

Info severity shows a blue squiggly underline in code and can be filtered separately from errors and warnings in the problems panel.

![image](https://user-images.githubusercontent.com/13839236/84826931-ffca1880-b023-11ea-8080-5e5b91a6ac0d.png)

Hint severity doesn't show up in the problems panel at all and only show three dots under the affected code or just faded text if the diagnostic also has the unnecessary tag.

### Solution
The solution provided by this PR allows the user to configure lists of of warnings to report as info severity and hint severity respectively. I purposefully only convert warnings and not errors as i believe it's a good idea to have the editor show the same severity as the compiler as much as possible.

### Open questions
#### Discoverability
How do we teach this to new and existing users? Should a section be added to the user manual? If so  where and what should it say?

#### Defaults
Other languages such as TypeScript report unused code as hint by default. Should rust-analyzer similarly report some problems as hint/info by default?

3c72fc0573 Anchor file-system operations to the file, and not to the source root. 
Anchoring to the SourceRoot wont' work if the path is absolute:

  #[path = "/tmp/foo.rs"]
  mod foo;

Anchoring to a file will.

However, we *should* anchor, instead of just producing an abs path.

I can imagine a situation where, for example, rust-analyzer processes
crates from different machines (or, for example, from in-memory git
branch), where the same absolute path in different crates might refer
to different files in the end!
