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?

61a60ce7d3 Auto merge of #61229 - Centril:stabilize-repr_align_enum, r=nagisa 
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.

08ede49dcb Remove redundant, commented out code 
It was commented out as part of
8a8e497ae7.
Done probably by accident, since the code in question was moved to a
match arm, along with newly introduced logic to detect bare CRs in raw
strings.

Rollup merge of #61616 - petrochenkov:parsderef, r=oli-obk 
parser: Remove `Deref` impl from `Parser`

Follow up to https://github.com/rust-lang/rust/pull/61541

You have to write `self.token.span` instead of `self.span` in the parser now, which is not nice, but not too bad either, I guess.
Not sure.
Probably still better than people using both and being confused about the definition point of `span`.

c1c60d292e Auto merge of #61209 - matthewjasper:const-tuple-constructors, r=oli-obk 
Make tuple constructors real const fns

Mir construction special cases `Ctor(...)` to be lowered as `Ctor { 0: ... }`, which means this doesn't come up much in practice, but it seems inconsistent not to allow this.
