Description:
------------
The property ReflectionClassConstant::$class is documented as:

http://php.net/manual/en/class.reflectionclassconstant.php#reflectionclassconstant.props

> Name of the class where the class constant is defined.

When using a hierarchy of classes and having constants defined on multiple levels this does return the child class where the constant is not defined.

Although using ReflectionClassConstant::getDeclaringClass() returns the correct one. In fact these two should point to the same class.

Test script:
---------------
https://3v4l.org/f0WZf

Expected result:
----------------
ReflectionClassConstant::class should return the class where the constant is really declared as stated in the docs.

This would also mean, that $constant->class === $constant->getDeclaringClass()->getName() is true.

This would also bring the constants in line with methods and properties, where this works correctly (as can be seen for example here https://3v4l.org/rqUF2).
