====== Enumerations ======
Enumerations are supported. In an enum class two synthetic methods are created in the Bystecode.
  * values(): returns an array with all values, uses //System.arraycopy//
  * valueOf(String name): returns the value with the name //name//. This method calls //valueOf// of the class //Enum//. Though with a slightly different signature than what is present in our runtime library. That's why this case must be specially handled by the class file reader. Further, in the SSA a reference to the field //ENUM$VALUES// (which is synthetic as well) must be loaded. Finally, during code generation the address of this field has to be loaded and the reference to it must be fetched.
\\
If enum values are used in a switch statement, a special field //$SWITCH_TABLE$CLASSNAME// will be created in the class with the switch statement. Further, a method is generated with the signature //static int[] $SWITCH_TABLE$CLASSNAME()//. This method is called before the first use of the switch statement. It initializes an int-array with the ordinal numbers of the enum entries. \\
