BATTLE.BIN : - Some_type_of_checking_algorithm
Unflag Ability from being Usable if it only adds an undesired status. This routine is to prevent the AI from using unnecessary status adding abilities if they are not needed, such as Shell vs a team that has no Magic damage whatsoever.
------------------------------------------------------------------------------------------
Parameter : r4 = Ability pointer (Unit usable AbilityList 8019f3c4 - 0x0ef0 Table )
r5 = Undesired status
