If lhs_type is unsigned and rhs_type is signed, check whether it can represent all of the values of lhs_type.
If not, then promote rhs_type to the unsigned version of its type. This expects that Rank(lhs_type) < Rank(rhs_type).

As a preparation for type casting, compare the requested 'target' type of the cast with the type of the operand to be cast.
If the cast is allowed, return the appropriate CastKind for the cast; otherwise return an error.
