Log message:
	Improved the functions `eliminate_null_decrements()' and
	`eliminate_negative_decrements()' not using more the method
	`Expr::match()'.
	Fixed a bug in the function `eliminate_negative_decrements()'.
	
	In the cases HAS_NEGATIVE_DECREMENT and HAS_NULL_DECREMENT of the
	function `solve_try_hard()' called recursively the function
	`solve_try_hard()' (and not `solve_easy_cases()' because in a
	recurrence could be at the same time cases of null decrement and
	cases of negative decrement).
