All visual design credit goes to @johnwhelchel (#37856)
Group "missing variable bind" spans in `or` matches and clarify wording
for the two possible cases: when a variable from the first pattern is
not in any of the subsequent patterns, and when a variable in any of the
other patterns is not in the first one.
Before:
```
error[E0408]: variable `a` from pattern #1 is not bound in pattern #2
--> file.rs:10:23
|
10 | T::T1(a, d) | T::T2(d, b) | T::T3(c) | T::T4(a) => { println!("{:?}", a); }
| ^^^^^^^^^^^ pattern doesn't bind `a`
error[E0408]: variable `b` from pattern #2 is not bound in pattern #1
--> file.rs:10:32

10 | T::T1(a, d) | T::T2(d, b) | T::T3(c) | T::T4(a) => { println!("{:?}", a); }
| ^ pattern doesn't bind `b`
error[E0408]: variable `a` from pattern #1 is not bound in pattern #3

10 | T::T1(a, d) | T::T2(d, b) | T::T3(c) | T::T4(a) => { println!("{:?}", a); }

```
After:
```

20 | T::T1(a, d) | T::T2(d, b) | T::T3(c) | T::T4(a) => {

```
* Have only one presentation for binding consistency errors
* Point to same binding in multiple patterns when possible
* Check inconsistent bindings in all arms
* Simplify wording of diagnostic message
* Sort emition and spans of binding errors for deterministic output
Inline function to avoid naming confusion.
Fixes the non-RFC requiring portion of #18394. The suggestion for a new token there probably needs to either be refiled onto rust-lang/rfcs if it's still relevant (may not be given Macros 2.0 work, not sure).
Move the reference into a submodule
Part of https://github.com/rust-lang/rust/issues/39588
This moves the reference out into its own submodule. Right now, it's under my own account; I would assume that it should go under `rust-lang`, but I guess there's an argument for the nursery too? I can fix that up before we commit it.
r? @alexcrichton @brson
Let `-Crelocation-model` better control `-pie` linking
Prior to this, if relocation model in the target options was "pic", as
most targets have it, then the user's `-Crelocation-model` had no effect
on whether `-pie` would be used. Only `-Clink-arg=-static` would have a
further override here.
Now we use `context::get_reloc_model`, which gives precedence to the
user's option, and if it's `RelocMode::PIC` we enable `-pie`. This is
the same test as `context::is_pie_binary`, except that folds across all
`sess.crate_types`, not just the current one.
Fixes#35061.
