Float/Float/Fly movements

Parameters : r4 = unit data pointer
Return r2 = holding various flags
            0x01 - 
            0x02 - Unit uses silent walk movement skill
            0x04 -
            0x08 - Unit uses Teleport*Teleport 2 (never with 0x80)
            0x10 - Unit uses move in water (never with 0x20, 0x40)
            0x20 - Unit uses move on water (never with 0x10, 0x40)
            0x40 - Unit is floating (never with 0x10,0x20)
            0x80 - Unit is flying (never with 0x08)
