In my limited understanding of the code, if actual_precision or from_unsignedN are different from the properties of typeN, we want to cast, and similarly we want to cast if TREE_TYPE (rhsN) is not uselessly convertible to typeN. For INTEGER_CSTs, such casts should be done using fold_convert always, otherwise build_and_insert_cast.
