Return values up to 128 bits in registers

This fixes https://github.com/rust-lang/rust/issues/26494#issuecomment-619506345 by making Rust's default ABI pass return values up to 128 bits in size in registers, just like the System V ABI.

The result is that these methods from the comment linked above now generate the same code, making the Rust ABI as efficient as the `"C"` ABI:

```rust
pub struct Stats { x: u32, y: u32, z: u32, }

pub extern "C" fn sum_c(a: &Stats, b: &Stats) -> Stats {
    return Stats {x: a.x + b.x, y: a.y + b.y, z: a.z + b.z };
}

pub fn sum_rust(a: &Stats, b: &Stats) -> Stats {
    return Stats {x: a.x + b.x, y: a.y + b.y, z: a.z + b.z };
}
```

```asm
sum_rust:
	movl	(%rsi), %eax
	addl	(%rdi), %eax
	movl	4(%rsi), %ecx
	addl	4(%rdi), %ecx
	movl	8(%rsi), %edx
	addl	8(%rdi), %edx
	shlq	$32, %rcx
	orq	%rcx, %rax
	retq
```

Rollup merge of #77209 - jyn514:fix-docs, r=petrochenkov 
Fix documentation highlighting in ty::BorrowKind

Previously it looked a little odd: https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/enum.BorrowKind.html#variant.UniqueImmBorrow

Noticed this while reviewing https://github.com/rust-lang/rustc-dev-guide/pull/894.

5b9e886403 Auto merge of #73453 - erikdesjardins:tuplayout, r=eddyb 
Ignore ZST offsets when deciding whether to use Scalar/ScalarPair layout

This is important because Scalar/ScalarPair layout previously would not be used if any ZST had nonzero offset.
For example, before this change, only `((), u128)` would be laid out like `u128`, not `(u128, ())`.

Fixes #63244

There changes are currently still untested, so I don't expect this to pass CI 😆
