It can't use `maybe_whole`, but it can match `maybe_whole` more closely.
Also add a test for a case that wasn't previously covered.

Properly recover from trailing attr in body
...
When encountering an attribute in a body, we try to recover from an
attribute on an expression (as opposed to a statement). We need to
properly clean up when the attribute is at the end of the body where a
tail expression would be.
Fix #118164 .

Handle attempts to have multiple cfgd tail expressions
...
When encountering code that seems like it might be trying to have
multiple tail expressions depending on `cfg` information, suggest
alternatives that will success to parse.
```rust
fn foo() -> String {
#[cfg(feature = "validation")]
[1, 2, 3].iter().map(|c| c.to_string()).collect::<String>()
#[cfg(not(feature = "validation"))]
String::new()
}
```
```
error: expected `;`, found `#`
--> $DIR/multiple-tail-expr-behind-cfg.rs:5:64
|
LL | #[cfg(feature = "validation")]
| ------------------------------ only `;` terminated statements or tail expressions are allowed after this attribute
LL | [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>()
| ^ expected `;` here
LL | #[cfg(not(feature = "validation"))]
| - unexpected token
|
help: add `;` here
|
LL | [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>();
| +
help: alternatively, consider surrounding the expression with a block
|
LL | { [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>() }
| + +
help: it seems like you are trying to provide different expressions depending on `cfg`, consider using `if cfg!(..)`
|
LL ~ if cfg!(feature = "validation") {
LL ~ [1, 2, 3].iter().map(|c| c.to_string()).collect::<String>()
LL ~ } else if cfg!(not(feature = "validation")) {
LL ~ String::new()
LL + }

```
