I added some comments. I hope they make things clearer.

The `functionMustProgress` call applies the C++ rules. So C++11 and above is
already handled by the call.
Afterwards, loops with constant conditions never have to make progress (C++
before 11, any C version). Loops with non-constant conditions have to make
progress in C11 and later.
Hopefully the comment makes that clearer.
