Member predicate ClassAggregateLiteral::isValueInitialized

Holds if the field field is value initialized because it is not explicitly initialized by this initializer list.

Value initialization (see [dcl.init]/8) recursively initializes all fields of an object to false, 0, nullptr, or by calling the default constructor, as appropriate to the type.
