isl_basic_map_foreach_constraint: make sure input has been finalized
Each constraint gets a copy of the input and a line from the constraint
matrix of the input. If the input wouldn't be finalized, then the copy
would create a duplicate and then the line wouldn't match the basic map.
This is problematic for especially isl_constraint_is_equality.
