Hi @fhahn, I'll take a look at addressing your comments in a follow-up patch. I had used the term speculative for things like `HasSpeculativeEarlyExit` to try and indicate that even the loop has to have more than just an uncountable early exit, because the exit count from the latch needs to be countable too in order for this flag to be true. But perhaps that's unnecessary and a bit pedantic and I think I'm happy to rename for consistency.
