To reproduce the changes in this commit locally:

- Run `./x test tidy` and remove all the output files not associated
  with a test file anymore, as reported by tidy.
- Run `./x test tests/mir-opt --bless` to generate the new outputs.

make sure the standard library compiles properly with synthetic targets 
It might happen that a synthetic target name does not match one of the
hardcoded ones in std's build script, causing std to fail to build. This
commit changes the std build script avoid including the restricted-std
feature unconditionally when a synthetic target is being built.

This PR adds help messages for these cases:

```rust
fn main() {
    let ptr1: *const u32 = std::ptr::null();

    let a = ptr1 + 5;
    let b = ptr1 - 5;
    let c = ptr2 - ptr1;
    let d = ptr1[5];

Rollup merge of #112528 - jyn514:fix-debuginfo-level, r=Mark-Simulacrum 
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.

81c02da94e Auto merge of #111958 - notriddle:notriddle/type-search-slice-array, r=GuillaumeGomez 
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.

rustdoc: Add `item_template` macro

Closes #112021

This change removes the use of `self.borrows()` in Askama templates, removes code duplication from `item_and_mut_cx()`, and improved readability by eliminating the prefix `item_template_` when calling from the template.

Static loading `ntdll` functions does not work for UWP programs, which will end up link errors complaining about missing symbols, or failure to pass the WACK tests. The breakage was introduced in #108262.

This PR basically reverts part of the changes in #108262 for UWP only, and fixes some lint suggestions.
