[NFC] Decoupling the unrolling logic into three different functions. The shouldPragmaUnroll() covers the 1st and 2nd priorities of the previous code, the shouldFullUnroll() covers the 3rd, and the shouldPartialUnroll() covers the 5th. The output of each function, Optional<unsigned>, could be a value for UP.Count, which means unrolling factor has been set, or None, which means decision hasn't been made yet and should try the next priority.
