------------------------------------------------------------------------------------------
Parameters - r4 : Considered Unit data pointer (Battle stats)
             
Returns r2 : Remaining Ticks before unit get an active turn

Notes

Mechanics
Test Status freezing CT that will not fade
Add Stop CT to the remaining Ticks

Bugs ?
No checks for don't act ? (When looking to returns location, it seems this routine is focusing on the unit getting a turn or not, i guess the don't act check will occurs later)
Sleep is checked as if the unit CT is not frozen

Hard coding
AI checks Status ID and not [freeze CT] flag for Crystal, Treasure, Petrify and Stop

Return Locations
