We add support for `return` and `raise` statements in the control flow graph: we simply add an edge to the terminal block, push the statements to the current block, and proceed. This implementation will have to be modified somewhat once we add support for `try` statements - then we will need to check whether to _defer_ the jump. But for now this will do! Also in this PR: We fix the `unreachable` diagnostic range so that it lumps together consecutive unreachable blocks.
