It does say that, and I expect cases can be constructed where the comment is true, but it is not
completely right. When you replace 2 copies of code with 1 copy you are generally making it
smaller. Plus, there is a beneficial interaction with RTL invariant hoisting, as it exposes more
invariants when you do hoisting inside a loop.
