If true, then there may exist break 'a
values that aim to
break out of this block early.
Used by 'label: {}
blocks and by catch
statements.

If true, don't emit return value type errors as the parser had to recover from a parse error so this block will not have an appropriate type. A parse error will have been emitted so the compilation will never succeed if this is true.
