Learn on hit 1

Duplicated page here : Process_Learn_on_Hit

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
