deed44a472 Remove support for jemalloc
We only used it for measuring memory usage, but now we can use glibc's
allocator for that just fine

5479: Allow gathering memory stats on non-jemalloc Linux r=matklad a=jonas-schievink

I could also parse `/proc/$PID/statm` to get the resident set size, but decided against that for now as it isn't terribly useful.

Note that `mallinfo()` is incredibly slow for some reason, and unfortunately this will be exposed to users via the "Memory Usage" command (even worse, the opened document will show the outdated values while the server is processing). So, not very ideal, but it keeps me from recompiling r-a with different feature sets all the time.

5451: Highlight more cases of SyntaxKind when it is a punctuation r=matklad a=GrayJack

This maybe closes #5406
Closes  #5453

Separate what one expect to be a punctuation semantic token (like `,`, `;`, `(`, etc), and what is not (`&`, `::`, `+`, etc)

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.

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`:

8aa10c00a4/crates/expect/src/lib.rs (L263)

(I have no idea why it thinks that `usize` is an `Iterator`)

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
```
