CompoundAssignOperator - For compound assignments (e.g.
+=), we keep track of the type the operation is performed in. Due to the semantics of these operators, the operands are promoted, the arithmetic performed, an implicit conversion back to the result type done, then the assignment takes place. This captures the intermediate type which the computation is done in.
