FieldDefinition :
ClassElementName Initializer_opt
InitializeInstanceFields ( O, constructor )
1. Assert: Type ( O ) is Object.
2. Assert: constructor is an ECMAScript function object.
3. Let fields be the value of constructor.[[Fields]].
4. For each item fieldRecord in order from fields,
a. Perform ? DefineField(O, fieldRecord).
5. Return.
DefineField(receiver, fieldRecord)
1. Assert: Type(receiver) is Object.
2. Assert: fieldRecord is a Record as created by ClassFieldDefinitionEvaluation.
3. Let name be fieldRecord.[[Name]].
4. Let initializer be fieldRecord.[[Initializer]].
5. If initializer is not empty, then
a. Let initValue be ? Call(initializer, receiver).
