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.

using a static string is just as ergonomic, if not more, and there's

2895: Rewrite ra_prof's profile printing r=michalt a=michalt
This changes the way we print things to first construct a mapping from
events to the children and uses that mapping to actually print things.
It should not change the actual output that we produce.
The new approach two benefits:
* It avoids a potential quadratic behavior of the previous approach.
For instance, for a vector of N elements:
```
[Message{level: (N - 1)}, ..., Message{level: 1}, Message{level: 0}]
```
we would first do a linear scan to find entry with level 0, then
another scan to find one with level 1, etc.
* It makes it much easier to improve the output in the future, because
we now pre-compute the children for each entry and can easily take
that into account when printing.

Fix a corner case when printing unaccounted time
...
Previously `ra_prof` wouldn't actually print the unaccounted time in
some cases.
We would print, for instance, this:
```
5ms - foo
2ms - bar
```
instead of:
```
5ms - foo
2ms - bar
3ms - ???
```
The fix is to properly handle the case when an entry has 0 children
instead of using the `last` variable.

Improve profiling output when duration filter is specified
...
In particular:
- Use strict inequality for comparisons, since that's what the filter
syntax supports.
- Convert to millis for comparisons, since that's the unit used both
for the filter and when printing.
Now something like `RA_PROFILE='*>0'` will only print things that took
at least 1ms (when rounded to millis).

allow rustfmt to reorder imports
...
This wasn't a right decision in the first place, the feature flag was
broken in the last rustfmt release, and syntax highlighting of imports

...
Now, one can use `let _p = ra_prof::cpu_profiler()` to capture profile

See the docs on https://github.com/AtheMathmo/cpuprofiler for more!
