Used by the routine at CheckObjectHitByShot.
Sets the bit for the map cell of an object in the bitmap at CurrentPlayerState_MapCells (found by FindCellBit), unless the item number in A is below 06. The bit number is written straight into the operand of the SET instruction at AC05, so this routine modifies its own code.
