Flow analysis unit tests now support implicit branch targets, and use
`LabeledStatement` directly in the case where the branch target is
explicit. This is more similar to how the language acutally behaves,
and paves the way for adding more sophisticated tests in the future.
Note that at the moment, there are no flow analysis tests where a
`continue` statement has a different target than the innermost loop,
so for now, the `continue_` function doesn't accept a target
parameter. I plan to add this functionality in the future, at the
time that I add tests that require it.
