rustdoc: properly calculate line length for where clauses
Apparently, while I was cleaning up #37190, I regressed the formatting for long where clauses, where it wouldn't take the "prefix" length into account when deciding whether to break the line up. This patch fixes that.
Advertise Vec in LinkedList docs
r? @steveklabnik
Hi! We already [advise](https://doc.rust-lang.org/std/collections/#use-a-linkedlist-when) to use `Vec` instead of `LinkedList` in the top-level collections documentation. But I think it may be missed by someone who just directly finds `LinkedList`.
What do you feel about advertising `Vec` directly in `LinkedList` docs as well?
Simplify notes on testing and concurrency
The start of the notes on tests running concurrently, added in https://github.com/rust-lang/rust/pull/37766 read a little awkwardly. This PR fixes that and simplifies the wording a bit.

std: Fix partial writes in LineWriter
Previously the `LineWriter` could successfully write some bytes but then fail to
report that it has done so. Additionally, an erroneous flush after a successful
write was permanently ignored. This commit fixes these two issues by (a)
maintaining a `need_flush` flag to indicate whether a flush should be the first
operation in `LineWriter::write` and (b) avoiding returning an error once some
bytes have been successfully written.
Closes#37807
Prevent where < ident > from parsing.
In order to be forward compatible with `where<'a>` syntax for higher
rank parameters, prevent potential conflicts with UFCS from parsing
correctly for the near term.
Disable field reordering
This was decided via IRC and needs a backport to beta. Basically, #37429 broke servo, and probably needs an announcement and opt-in flag. I didn't run all tests locally but think I've already reverted all the ones that need to be reverted.

Allow legacy custom derive authors to disable warnings in downstream crates
This PR allows legacy custom derive authors to use a pre-deprecated method `registry.register_custom_derive()` instead of `registry.register_syntax_extension()` to avoid downstream deprecation warnings.

Redox Cross Compilation
I will admit - there are things here that I wish I did not have to do. This completes the ability to create a cross compiler from the rust repository for `x86_64-unknown-redox`. I will document this PR with inline comments explaining some things.
[View this gist to see how a cross compiler is built](https://gist.github.com/jackpot51/6680ad973986e84d69c79854249f2b7e)
Prior discussion of a smaller change is here: https://github.com/rust-lang/rust/pull/38366
Refactor global paths
This PR removes the field `global: bool` from `ast::Path` and `hir::Path`, instead representing a global path `::foo::bar` as `{{root}}::foo::bar`, where `{{root}}` is a virtual keyword `keywords::CrateRoot`.
Also, fixes#38016.

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.
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.
