Parameters:
r4 = (actingUnitIndex) Battle unit index of acting unit
r5 = (learnedAbilityStorePtr) Pointer for storing learned ability ID
Returns:
r2 = (Unit index) of unit that learned the ability
r2 = -1 if no used ability or used ability is not flagged as Learn on Hit, or no unit learned the ability
