Get Overlapping Unit Misc Data Pointer

#   ROUTINE: GET OVERLAPPING UNIT MISC DATA POINTER
#       Checks if there is a unit on the specified (X, Y, HigherElevation coordinates) separate from the specified unit and returns its (Unit misc data pointer) if so.
#       Prefers the pointer at 0x80196118, if it matches.
#       Parameters:
#           r4 = (p_MiscData) Unit misc data pointer
#           r5 = (p_X) X Coordinate
#           r6 = (p_Y) Y Coordinate
#           r7 = (p_HigherElevation) Higher Elevation
#       Returns:
#           r2 = (Unit misc data pointer) of a unit on the specified coordinates that is not the specified unit and not the specified unit's rider (if the specified unit is a mount),
#               or returns null if no such unit could be found.
