fa7a3c210d Auto merge of #29484 - steveklabnik:gh29330, r=brson
These two commits do a few things:

1. reformat to 80 cols
2. use the reference-style links where appropriate for improved in-source readability
3. adds a few links, tweaks a couple of words, `3` -> `three`, stuff like that

While the diff is big due to these edits, there's no significant content change.

11ba81e105 Auto merge of #29477 - alexcrichton:revert-compiler-rt, r=brson
This ended up causing regressions in a few builds I've seen:

* MinGW -- [64-bit](https://ci.appveyor.com/project/alexcrichton/gcc-rs/build/1.0.338/job/2c4pkxgxa2dvqs25) and [32-bit](https://ci.appveyor.com/project/alexcrichton/gcc-rs/build/1.0.338/job/d0n7kml3k5el9gla)
- MSVC - [64-bit with VS 12.0](https://ci.appveyor.com/project/alexcrichton/gcc-rs/build/job/ugldcage9ydoy1k6) and [32-bit with VS 12.0](https://ci.appveyor.com/project/alexcrichton/gcc-rs/build/job/pn59p4rhnj8gybei).

I suspect the problems are along the lines of:

* The emutls support needs to be disabled on Windows, it currently always used pthreads which isn't available
* The objects in compiler-rt either need to be built without a CRT or not specifically against the static one.

64b0277643 Auto merge of #29454 - stepancheg:vec-reserve, r=bluss
Before this patch `reserve` function allocated twice as requested
amount elements (not twice as capacity).  It leaded to unnecessary
excessive memory usage in scenarios like this:

```
let mut v = Vec::new();
v.push(17);
v.extend(0..10);
println!("{}", v.capacity());
```

`Vec` allocated 22 elements, while it could allocate just 11.

`reserve` function must have a property of keeping `push` operation
cost (which calls `reserve`) `O(1)`. To achieve this `reserve` must
exponentialy grow its capacity when it does reallocation.

There's better strategy to implement `reserve`:

```
let new_capacity = max(current_capacity * 2, requested_capacity);
```

This strategy still guarantees that capacity grows at `O(1)` with
`reserve`, and fixes the issue with `extend`.

Patch imlpements this strategy.

a18e0b2707 Auto merge of #29445 - igpay:patch-1, r=alexcrichton
This documentation confused me when trying to use truncate on a project. Originally, it was unclear whether truncate removed the last `len` elements, or whether it cut down the vector to be exactly `len` elements long. The example was also ambiguous.

427140f771 Auto merge of #29188 - nikomatsakis:remove-contraction, r=pnkfelix
This fixes #29048 (though I think adding better transactional support would be a better fix for that issue, but that is more difficult). It also simplifies region inference and changes the model to a pure data flow one, as discussed in [this internals thread](https://internals.rust-lang.org/t/rough-thoughts-on-the-impl-of-region-inference-mir-etc/2800). I am not 100% sure though if this PR is the right thing to do -- or at least maybe not at this moment, so thoughts on that would be appreciated.

2af9aabf3a Auto merge of #29441 - Ryman:match_refactor_msg, r=alexcrichton
This helps for the case where a match, such as below:
```rust
let foo = match foo {
    Some(x) => x,
    None => 0
};
```
gets refactored to no longer need the match, but the match keyword has been left accidentally: 

```rust
let foo = match foo.unwrap_or(0);
```

This can be hard to spot as the expression grows more complex.

This is an alternative to https://github.com/rust-lang/rust/pull/29240 which fixes #15307 by adding colors to primitives and aliases instead of underlining.

Try to keep the discussion in https://github.com/rust-lang/rust/pull/29240 for now though so it can be kept track of.
