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.

Hopefully fixes power 32-bit build.

5270: Add argument count mismatch diagnostic r=matklad a=jonas-schievink
Closes https://github.com/rust-analyzer/rust-analyzer/issues/4025.
This currently has one false positive on this line, where `max` is resolved to `Iterator::max` instead of `Ord::max`:
https://github.com/rust-analyzer/rust-analyzer/blob/8aa10c00a4c5b957d459fac5a103cd9688e8dcdd/crates/expect/src/lib.rs#L263
(I have no idea why it thinks that `usize` is an `Iterator`)
TODO:
* [x] Tests
* [x] Improve diagnostic text for method calls

Override miniz_oxide to build it with optimizations
Building this crate with optimizations decreases the gzipping
part of `cargo xtask dist` from `30-40s` down to `3s`,
the overhead for `rustc` to apply optimizations is miserable on this background

5142: analysis-stats: allow parallel type inference r=matklad a=jonas-schievink
This is mostly just for testing/fun, but it looks like type inference can be sped up massively with little to no effort (since it runs after the serial phases are already done).
Without `--parallel`:
```
Item Collection: 16.43597698s, 683mb allocated 720mb resident
Inference: 25.429774879s, 1720mb allocated 1781mb resident
Total: 41.865866352s, 1720mb allocated 1781mb resident
```
With `--parallel`:
```
Item Collection: 16.380369815s, 683mb allocated 735mb resident
Parallel Inference: 7.449166445s, 1721mb allocated 1812mb resident
Inference: 143.437157ms, 1721mb allocated 1812mb resident
Total: 23.973303611s, 1721mb allocated 1812mb resident
```

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 (:bulb:). 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

5120: Add a simple SSR subcommand to the rust-analyzer command line binary r=davidlattimore a=davidlattimore
Is adding the dependency on ra_ide_db OK? It's needed for the call to `db.local_roots()`
