It would not. `terminators()` uses `getFirstTerminator()` as the start iterator for the range, and therefore it only counts terminators which are adjacent instructions at the end of the block.

I'm open to other approaches to fix this, its just that a new terminator seemed like the least hacky approach, but it's not without it's own issues.
