test: Add case for implicit members of a const aggregate struct

A struct like

    struct foo {
      int const bar;
    };

cannot have an implicit default constructor but can be initialized
as an aggregate, e.g.

    foo f = {123};

Clang in C++11 mode and above correctly deletes the implicit default
constructor.  Add a test case covering this for C++11 and C++14.

Unfortunately Clang in C++98 mode does not mark the implicit default
constructor as invalid even after `Sema::MarkFunctionReferenced` has
been called.  Therefore CastXML incorrectly generates the member.
Add a "broken" test case to record this limitation.
