*
* An entity is the representation of program known objects in Firm.
* The primary concept of entities is to represent members of complex
*
* These fields can only be accessed via access functions.

+ * Overwrites is a field that specifies that an access to the overwritten
+ * entity in the supertype must use this entity. It's a list as with
+ * multiple inheritance several entities can be overwritten. This field
+ * is mostly useful for method entities.
+ * If a Sel node selects an entity that is overwritten by other entities it
+ * must return a pointer to the entity of the dynamic type of the pointer
+ * that is passed to it. Lowering of the Sel node must assure this.
+ * Overwrittenby is the inverse of overwrites. Both add routines add
+ * both relations, they only differ in the order of arguments.
