Added 3 hacks so that QtCore reaches the end of code generation:

1. If an expression of an enum item is null, count it as non-hex;
2. Do not throw a NotSupported exception when a fixed array of an non-primitive type is encountered;
3. Provide some seemingly correct implementation for CppTypePrinter.VisitTemplateParameterSubstitutionType.
