\brief register a callback when the solver decides to split on a registered expression.
The callback may set the passed expression to another registered expression which will be selected instead.
In case the expression is a bitvector the bit to split on is determined by the bit argument and the
truth-value to try first is given by is_pos. In case the truth value is undefined the solver will decide.
The callback may change the arguments by providing other values by calling \ref Z3_solver_next_split
