The target of a 'break' statement without a provided label must be a
regular block belonging to a surrounding loop or switch statement, named
blocks (i.e. the one that just define a label) on the other hand must be
targeted specifically with the provided label (and not implicitly). This
fixes the behavior by introducing a dedicated {BlockKind::kNamed} for
this purpose.
