[objc-arc] Move the before optimization statistics gathering phase out of OptimizeIndividualCalls.

Browse Source 
This makes the statistics gathering completely independent of the actual
optimization occuring, preventing any sort of bleeding over from occuring.

Additionally, it simplifies a switch statement in the non-statistic gathering case.
