Add deny(unused_lifetimes) to all the crates that have deny(internal).
@Zoxc brought up, regarding #61722, that we don't force the removal of unused lifetimes.
Turns out that it's not that bad to enable for compiler crates (I wonder why it's not `warn` by default?).
I would've liked to enable `single_use_lifetimes` as well, but https://github.com/rust-lang/rust/issues/53738 makes it unusable for now.
For the `rustfmt` commit, I used https://github.com/rust-lang/rustfmt/issues/1324#issuecomment-482109952, and manually filtered out some noise.

lexer: Disallow bare CR in raw byte strings
Handles bare CR ~but doesn't translate `\r\n` to `\n` yet in raw strings yet~ and translates CRLF to LF in raw strings.
As a side-note I think it'd be good to change the `unescape_` to return plain iterators to reduce some boilerplate (e.g. `has_error` could benefit from collecting `Result<T>` and aborting early on errors) but will do that separately, unless I missed something here that prevents it.
@matklad @petrochenkov thoughts?
Update RLS
This includes https://github.com/rust-lang/rls/pull/1482 which should finally fix the spurious tests RLS in Rust CI (test-pass -> test-fail).

Haiku: the maximum stack size is 16 MB
This keeps the compiler from crashing every time it is invoked. No functional change on other platforms.
This patch is similar to the limitation that is in the [librustdoc/lib.rs](57e13e0325/src/librustdoc/lib.rs (L89)).
get rid of real_intrinsics module
instead import intrinsics locally in their wrapper functions.
(These functions are wrapper functions as a preparation to fixing https://github.com/rust-lang/rust/issues/53871.)
Replaced linear token counting macros with optimized implementation
There are currently two distinct token-counting macros in the source. Both implement the trivial algorithm, with linear complexity. They may or may not be adequate for their use case, but considering that other people are probably going to copy and paste them whenever they need a token-counting macro, I replaced them with an optimized implementation with logarithmic complexity.
When one tries to create a thread with a requested stack size larger
than 16 MB, the call will fail and the compiler will bail out. Therefore
we should limit the size of the thread stack to 16 MB on Haiku.
Use Build::read_dir instead of fs::read_dir in Build::cp_r
Build::read_dir does better error handling when the directory doesn't
exist; it actually prints the name of the directory rather than just
printing the underlying error "No such file or directory" which on
its own isn't very useful.

Stabilize #![feature(repr_align_enum)] in Rust 1.37.0
On an `enum` item, you may now write:
```rust
#[repr(align(X))]
enum Foo {
// ...
}
```
This has equivalent effects to first defining:
```rust
#[repr(align(X))]
struct AlignX<T>(T);
```
and then using `AlignX<Foo>` in `Foo`'s stead.
