Emit while_true lint spanning the entire loop condition
The lint that suggests `loop {}` instead of `while true {}` has functionality to 'pierce' parenthesis in cases like `while (true) {}`. In these cases, the emitted span only went to the hi of the `true` itself, not spanning the entire loop condition.
Before:
```
warning: denote infinite loops with `loop { ... }`
--> /tmp/foobar.rs:2:5
|
2 | while ((((((true)))))) {}
| ^^^^^^^^^^^^^^^^ help: use `loop`
|
= note: `#[warn(while_true)]` on by default
```
After:
```
warning: denote infinite loops with `loop { ... }`
--> /tmp/foobar.rs:2:5
|
2 | while ((((((true)))))) {}
| ^^^^^^^^^^^^^^^^^^^^^^ help: use `loop`
|
= note: `#[warn(while_true)]` on by default
```
This is especially a problem for rustfix.
