Change Expression.isDeterministic() to return an ENUM with three values

DETERMINISTIC -  the expression returns the same output every time given the same input.
UNDETERMINISTIC_ROW - the expression should be computed for every row
UNDETERMINISTIC_STMT - the expression should be be computed for a given statement only once

See PHOENIX-1001
