Fix async desugaring providing wrong input to procedural macros.
Fixes #60674.
This PR fixes a minor oversight introduced by #60535 where unused `mut` binding modes were removed from the arguments to an `async fn` (as they were added to the statement that we insert into the closure body). However, this meant that the input to procedural macros was incorrect. This removes that and instead fixes the `unused_mut` error that it avoided.

Skip codegen for one UI test with long file path
The path to this test is so long that object files produced by it hit some path length limit on Windows and linker cannot find them.
The workaround here is to skip codegen and avoid producing object files, this test doesn't need them anyway.

Identify when a stmt could have been parsed as an expr
There are some expressions that can be parsed as a statement without

confusing errors due to the same looking code being accepted in some
places and not others. Identify these cases and suggest enclosing in
parenthesis making the parse non-ambiguous without changing the
accepted grammar.

This commit removes the modification of the mutability of simple
bindings. While the mutability isn't used, it is important that it is
kept so that the input to procedural macros matches what the user wrote.

Inline some Cursor calls for slices
(Partially) brings back https://github.com/rust-lang/rust/pull/33921
I've noticed in some serialization code I was writing that writes to slices produce much, much, worse code than you'd expect even with optimizations turned on. For example, you'd expect something like this to be zero cost:
```
use std::io::{self, Cursor, Write};
pub fn serialize((a, b): (u64, u64)) -> [u8;8+8] {
let mut r = [0u8;16];
{
let mut w = Cursor::new(&mut r[..]);
w.write(&a.to_le_bytes()).unwrap();
w.write(&b.to_le_bytes()).unwrap();
}
r
}
```
...but it compiles down to [dozens of instructions](https://rust.godbolt.org/z/bdwDzb) because the `slice_write()` calls aren't inlined, which in turn means `unwrap()` can't be optimized away, and so on.
To be clear, this pull-req isn't sufficient by itself: if we want to go down that path we also need to add `#[inline]`'s to the default implementations for functions like `write_all()` in the `Write` trait and so on, or implement them separately in the `Cursor` impls. But I figured I'd start a conversation about what tradeoffs we're expecting here.
