[PATCH] Cleanup early-exit from analyzeCall

[Chandler Carruth]

I think it would even more clear to reverse everything.

Add all of the possible bonuses to the threshold, and when they cease to apply, subtract them, including subtracting any part of the vector bonus that ended up not applying at the very end.

That makes it more clear that this doesn't meaningfully change the bounds on how much of the function we look at, and there aren't two thresholds at all. We just need to have the threshold always be the max of all possible bonuses which could apply.

(It would be good to update the commit log message as well to be more clear that this doesn't cause us to look at the entire function, just to assume the maximum bonuses will apply until proven wrong.)
