support config extensions
_Copied from the `rustc-dev-guide` addition:_
>When working on different tasks, you might need to switch between different bootstrap >configurations.
>Sometimes you may want to keep an old configuration for future use. But saving raw config >values in
>random files and manually copying and pasting them can quickly become messy, especially if >you have a
>long history of different configurations.
>
>To simplify managing multiple configurations, you can create config extensions.
>
>For example, you can create a simple config file named `cross.toml`:
>
>```toml
>[build]
>build = "x86_64-unknown-linux-gnu"
>host = ["i686-unknown-linux-gnu"]
>target = ["i686-unknown-linux-gnu"]
>
>
>[llvm]
>download-ci-llvm = false
>
>[target.x86_64-unknown-linux-gnu]
>llvm-config = "/path/to/llvm-19/bin/llvm-config"
>```
>
>Then, include this in your `bootstrap.toml`:
>
>```toml
>include = ["cross.toml"]
>```
>
>You can also include extensions within extensions recursively.
>
>**Note:** In the `include` field, the overriding logic follows a right-to-left order. For example,
in `include = ["a.toml", "b.toml"]`, extension `b.toml` overrides `a.toml`. Also, parent extensions
always overrides the inner ones.

- Rust backcompat removes the need to specify the version here
- Using these commands can result in a needless toolchain getting
downloaded, like in the case where user only has Nightly installed

Rename `LifetimeName` as `LifetimeKind`.
It's a much better name, more consistent with how we name such things.
Also rename `Lifetime::res` as `Lifetime::kind` to match. I suspect this field used to have the type `LifetimeRes` and then the type was changed but the field name remained the same.

Remind to update dev branch while behind too many commits

In particular, `borrowck_graphviz_preflow` no longer exists.

Coding conventions chapter cleaning
|
|
- use correct code block markers
- add missing title
- rustfmt can now use edition setting in its config
... and this is set in Rust repo
- reduce visual noise
- needless repetition
- convention is to start sentence with upper case
- sembr
- whitespace
- semi-heading not adding much value
- fix grammar

Remove old references to the HIR map.

compiletest: Make `SUGGESTION` annotations viral
If one of them is expected in a test file, then others should be annotated as well, in the same way as with `HELP`s and `NOTE`s.
This doesn't require much of an additional annotation burden, but simplifies the rules.

1. added two new parts: Bootstrapping and Supporting Infrastructure;
2. touched up names of pre-existing parts, to match actual names in sidebar;
3. syntactic nits (start description of Analysis with a capital letter); and
4. make numbered list use only 1.

Fix breakage when running compiletest with `--test-args=--edition=2015`
Compiletest has an `--edition` flag to change the default edition tests are run with. Unfortunately no test suite successfully executes when that flag is passed. If the edition is set to something greater than 2015 the breakage is expected, since the test suite currently supports only edition 2015 (Ferrous Systems will open an MCP about fixing that soonish). Surprisingly, the test suite is also broken if `--edition=2015` is passed to compiletest. This PR focuses on fixing the latter.
This PR fixes the two categories of failures happening when `--edition=2015` is passed:
* Some edition-specific tests set their edition through `//@ compile-flags` instead of `//@ edition`. Compiletest doesn't parse the compile flags, so it would see no `//@ edition` and add another `--edition` flag, leading to a rustc error.
* Compiletest would add the edition after `//@ compile-flags`, while some tests depend on flags passed to `//@ compile-flags` being the last flags in the rustc invocation.
Note that for the first category, I opted to manually go and replace all `//@ compile-flags` setting an edition with an explicit `//@ edition`. We could've changed compiletest to instead check whether an edition was set in `//@ compile-flags`, but I thought it was better to enforce a consistent way to set the edition in tests.
I also added the edition to the stamp, so that changing `--edition` results in tests being re-executed.
