 GeneratedMessageLite.ExtensionDescriptor descriptor,
 Class<?> singularType)

Create a new instance with the given parameters.

The last parameter singularType is only needed for enum types. We store integer values for enum types in a GeneratedMessageLite.ExtendableMessage and use Java reflection to convert an integer value back into a concrete enum object.
