make ui test output patch compatible #41948
Hello!
Previously with #41474 I've changed the internals of UI test output comparison mechanism.
That change didn't change the diff format that we were producing but we needed to improve it anyway.
This makes unified diff lines a little bit more `patch` compatible.
Also I tried to introduce a unit test to check this but couldn't decide which of the following to implement:
1. Should I replace `println` macros with `Writer`s? And access the produced output within a test?
2. Should I add an external test (something like `src/test/run-pass/command-exec.rs`)
3. There are crates that capture `stdout`. Are they safe to use here? (I don't think so)
Thanks!

Add better error message when == operator is badly used
Part of #40660.
With the following code:
```rust
fn foo<T: PartialEq>(a: &T, b: T) {
a == b;
}
fn main() {
foo(&1, 1);
}
```
It prints:
```
error[E0277]: the trait bound `&T: std::cmp::PartialEq<T>` is not satisfied
--> test.rs:2:5
|
2 | a == b;
| ^^^^^^ can't compare `&T` with `T`
|
= help: the trait `std::cmp::PartialEq<T>` is not implemented for `&T`
= help: consider adding a `where &T: std::cmp::PartialEq<T>` bound
error: aborting due to previous error
```
Ideally, we'd have the `Ty` inserted directly in the dep-node, but since
we can't do that yet, we extract the characteristic def-id of the type
in question.

Use the trait-environment+type as the key. Note that these
are only invoked on types that live for the entire compilation
(no inference artifacts). We no longer need the various special-case
bits and caches that were in place before.
It was decided in the RFC discussion https://github.com/rust-lang/rfcs/pull/1954 to make the function call syntax Rc::clone(&foo) the idiomatic way to clone a reference counted pointer (over the method call syntax foo.clone(). This change updates the documentation of Rc, Arc and their respoective Weak pointers to reflect it and bring more exposure to the existence of the function call syntax.
`Vec::into_boxed_slice` and `[T]::into_vec` are inverses, so it makes sense
to mention the other in their respective documentation for visibility.
`Vec::into_boxed_slice` already mentions `[T]::into_vec`, but not the other
way around until now.

Fixes#36556
bootstrap: fix minor comment typos in lib.rs
I noticed these while reading through the build system
documentation. They're hardly worth fixing, but I'm also using this to
get my feet wet with the rustc contribution system.

Not being an enum improves ergonomics, especially since NonEmpty could be Empty. It can still be iterable without an extra "done" bit by making the range have !(start <= end), which is even possible without changing the Step trait.
Implements RFC 1980
Update rust-installer to normalize manifest paths
This fixes the backslash-paths found in the manifests of installers that are built on Windows. This is the most problematic part of #42121, leaving just the non-executable install.sh.
