False positive for #smallLintTempsReadBeforeWritten when using #doWhileTrue:

The following method is falsely detected by the `#smallLintTempsReadBeforeWritten` check:
```
someMethod

	| x |
	[x := 1] doWhileTrue: [x <> 1].
```

**Additional context**
Fixing this issue would require do create a whitelist of BlockClosure messages that are guaranteed to evaluate the block before the argument blocks. Not sure whether this might be too complex ...
