Remove some erroneously added brackets_increment() calls. Reject <=> in preprocessor expressions with a clear error message (it seems it isn't supported here - clang and gcc don't at least). The type returned by `<=>` is not `bool`. We pretend it's `int` for now, which should work for how it's likely to be used in constant expressions. Fixes #1622
