Delete the llvm submodule lockfile when configuring on the bots
This should fix the periodic error that .git/modules/src/llvm/index.lock
exists on the mac slaves.
The Markdown engine used by the book can cope with a single leading space
on the list marker:
Like this:
* List item
Rather than like this:
* List item
… but it’s not the typical convention employed in the book, and moreover
the Markdown engine used for producing the error index *can’t* cope with
it (its behaviour looks like a bug, as it appears to lose one of the two
line breaks as well, but that’s immaterial here).
So, we shift to a single convention which doesn’t trigger bugs in the
Markdown renderer.
1.14 release notes
[Rendered](https://github.com/brson/rust/blob/relnotes/RELEASES.md).
Is there anything I'm missing? Were there any library stabilizations?
The most interesting thing this time seems to be rustup, then compile time opts, `..` matches, cargo exposing `cfg` values to build scripts. This release also has wasm support, but it's pretty rough. Might be worth hyping up all the same. ARM MUSL targets.
There are a large number of compatibility notes. Might be worth talking about that.

Cleanup old trans
This is a cleanup of old trans, with the following main points:
- Remove the `build.rs` API (prefer using `Builder` directly, which is now passed where needed through `BlockAndBuilder`).
- Remove `Block` (inlining it into `BlockAndBuilder`)
- Remove `Callee::call`, primarily through inlining and simplification of code.
- Thinned `FunctionContext`:
- `mir`, `debug_scopes`, `scopes`, and `fn_ty` are moved to `MirContext`.
- `param_env` is moved to `SharedCrateContext` and renamed to `empty_param_env`.
- `llretslotptr` is removed, replaced with more careful management of the return values in calls.
- `landingpad_alloca` is inlined into cleanup.
- `param_substs` are moved to `MirContext`.
- `span` is removed, it was never set to anything but `None`.
- `block_arena` and `lpad_arena` are removed, since neither was necessary (landing pads and block are quite small, and neither needs arena allocation).
- Fixed `drop_in_place` not running other destructors in the same function.
Fixes#35566 (thanks to @est31 for confirming).
mk: Fix compile with makefiles
A tweak was made to dependencies in #38451 but the makefiles weren't updated to
accompany this. Instead of trying to integerate the `build_helper` crate into
the makefiles (which currently isn't present) this commit takes the approach of
just duplicating the required logic, which should be small enough for now.
