The primary advantage of ungrammar is that it (eventually) allows one
to describe concrete syntax tree structure -- with alternatives and
specific sequence of tokens & nodes.
That should be re-usable for:
* generate `make` calls
* Rust reference
* Hypothetical parser's evented API
We loose doc comments for the time being unfortunately. I don't think
we should add support for doc comments to ungrammar -- they'll make
grammar file hard to read. We might supply docs as out-of band info,
or maybe just via a reference, but we'll think about that once things
are no longer in flux

It worked before, but was roundabout

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this will be exposed to users via the "Memory Usage" command (even worse, the opened document will show the outdated values while the server is processing).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)
5463: Bump lexer r=matklad a=kjeremy
Since we're now on rust 1.45
5465: Bump chalk r=matklad a=kjeremy
5466: Do not show default types in function and closure return values r=matklad a=SomeoneToIgnore
Avoid things like

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>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`:
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
