6f42153eac Ruby: Include empty StmtSequences in CFG
Empty StmtSequences appear, for example, in the `else` branch of `if`
statements like the following:

    foo

    if cond
      bar
    else
    end

    baz

Before this change, the CFG for this code would look like this:

        foo
         │
         │
         ▼
        cond
         │
    true │
         ▼
        bar
         │
         │
         ▼
         if
         │
         │
         ▼
        baz

i.e. there is linear flow through the condition, the `then` branch, and
out of the if. This doesn't account for the possibility that the
condition is false and `bar` is not executed. After this change, the CFG
looks like this:

          foo
           │
           │
           ▼
          cond
         │    │
    true │    │ false
         ▼    │
        bar   │
         │    │
         │    │
         ▼    ▼
           if
           │
           │
           ▼
          baz

i.e. we correctly account for the `false` condition.
