95d85899ce Add more measurements to the CGU debug printing.
For example, we go from this:
```
FINAL (4059 items, total_size=232342; 16 CGUs, max_size=39608,
min_size=5468, max_size/min_size=7.2):
- CGU[0] regex.f2ff11e98f8b05c7-cgu.0 (318 items, size=39608):
  - fn ...
  - fn ...
```
to this:
```
FINAL
- unique items: 2726 (1459 root + 1267 inlined), unique size: 201214 (146046 root + 55168 inlined)
- placed items: 4059 (1459 root + 2600 inlined), placed size: 232342 (146046 root + 86296 inlined)
- placed/unique items ratio: 1.49, placed/unique size ratio: 1.15
- CGUs: 16, mean size: 14521.4, sizes: [39608, 31122, 20318, 20236, 16268, 13777, 12310, 10531, 10205, 9810, 9250, 9065 (x2), 7785, 7524, 5468]

- CGU[0]
  - regex.f2ff11e98f8b05c7-cgu.0, size: 39608
  - items: 318, mean size: 124.6, sizes: [28395, 3418, 558, 485, 259, 228, 176, 166, 146, 118, 117 (x3), 114 (x5), 113 (x3), 101, 84, 82, 77, 76, 72, 71 (x2), 66, 65, 62, 61, 59 (x2), 57, 55, 54 (x2), 53 (x4), 52 (x5), 51 (x4), 50, 48, 47, 46, 45 (x3), 44, 43 (x5), 42, 40, 38 (x4), 37, 35, 34 (x2), 32 (x2), 31, 30, 28 (x2), 27 (x2), 26 (x3), 24 (x2), 23 (x3), 22 (x2), 21, 20, 16 (x4), 15, 13 (x7), 12 (x3), 11 (x6), 10, 9 (x2), 8 (x4), 7 (x8), 6 (x38), 5 (x21), 4 (x7), 3 (x45), 2 (x63), 1 (x13)]
  - fn ...
  - fn ...
```
This is a lot more information, distinguishing between root items and
inlined items, showing how much duplication there is of inlined items,
plus the full range of sizes for CGUs and items within CGUs. All of
which is really helpful when analyzing this stuff and trying different
CGU formation algorithms.

Rollup merge of #112527 - bdbai:fix/winarm32, r=ChrisDenton
Add windows_sys type definitions for ARM32 manually

`windows_sys` bindings do not include platform-specific type definitions for ARM 32 architecture, so it breaks `thumbv7a-pc-windows-msvc` and `thumbv7a-uwp-windows-msvc` targets. This PR tries to add them back by manually inserting them together with the generated ones.

`WSADATA` is copied from the generated definition for `x86`. `CONTEXT` is copied from the definition before `windows_sys` is introduced (which is just an empty enum): 4a18324a4d/library/std/src/sys/windows/c.rs (L802).

Fixes #112265.

bootstrap: Don't override `debuginfo-level = 1` to mean `line-tables-only`

This has real differences in the effective debuginfo: in particular, it omits the module-level information and makes perf less useful (it can't distinguish "self" from "child" time anymore).

Allow passing `line-tables-only` directly in config.toml instead.

See https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/debuginfo.20in.20try.20builds/near/365090631 and https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings/topic/.5Bsteering.5D.202023-06-09/near/364883519 for more discussion.

rustdoc: search for slices and arrays by type with `[]`

This feature extends rustdoc to support the syntax that most users will naturally attempt to use to search for slices and arrays. Part of #60485

Function signature searches already support arrays and slices. The explicit name `primitive:slice<u8>` and `primitive:array<u8>` can be used to match a slice or array of bytes, while square brackets `[u8]` will match either one. Empty square brackets, `[]`, will match any slice regardless of what it contains.

Preview:

* [`option -> []`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=option%20-%3E%20%5B%5D)
* [`[u8] -> str`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=%5Bu8%5D%20-%3E%20str)
* [`Box<[u8]> -> str`](https://notriddle.com/rustdoc-demo-html-3/search-slice-array/std/index.html?search=Box%3C%5Bu8%5D%3E%20-%3E%20str)

Motivation:

When type-based search was first landed, it was directly described as "incomplete". Here's [a comment] from the discussion thread:

[a comment]: https://github.com/rust-lang/rust/pull/23289#issuecomment-79437386

> This is looking really great, nice work! I can think of a number of cases that aren't quite covered by this, but I feel like this is a great improvement regardless and it can always be iterated on so I'm fine landing with a few known cases where it may not work :)

Filling out the missing functionality is going to mean adding support for more of Rust's [type expression] syntax, such as slices (in this PR), tuples, references, raw pointers, function pointers, and generics.

[type expression]: https://doc.rust-lang.org/reference/types.html#type-expressions

There does seem to be demand for this sort of thing, such as [this Discord message](https://discord.com/channels/442252698964721669/443150878111694848/1042145740065099796) expressing regret at rustdoc not supporting tuples in search queries.

Don't compile rustc to self-test compiletest

This was changed from stage 0 to 1 in https://github.com/rust-lang/rust/pull/108905, but I'm not sure why. Change it to `top_stage` instead to allow people to choose the stage.

This should save quite a bit of time in the `mingw-check` builder, which explicitly runs `x test --stage 0 compiletest`.

Note that this also fixes a latent bug that depended on running `x build compiler` before `x doc compiler`, as well as a couple cleanups related to symlinks (which made the latent bug easier to find).

rustdoc: re-elide cross-crate default trait-object lifetime bounds

Hide trait-object lifetime bounds (re-exported from an external crate) if they coincide with [their default](https://doc.rust-lang.org/reference/lifetime-elision.html#default-trait-object-lifetimes).
Partially addresses #44306. Follow-up to #103885. [Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/clean_middle_ty.3A.20I.20need.20to.20add.20a.20parameter/near/307143097).

Most notably, if `std` exported something from `core` containing a type like `Box<dyn Fn()>`, then it would now be rendered as `Box<dyn Fn(), Global>` instead of `Box<dyn Fn() + 'static, Global>` (hiding `+ 'static` as it is the default in this case). Showing `Global` here is a separate issue, #80379, which is on my agenda.

Note that I am not really fond of the fact that I had to add a parameter to such a widely used function (30+ call sites) to address such a niche bug.
