I'm not that familiar with references but presumably the idea is not to have
to think about the address otherwise you might as well use a pointer.

This changes to varobj.c look good to me.

        * gdb.mi/mi-cpp.exp: New file.
        * gdb.mi/mi-cpp.cpp: New file.

gdb.mi/mi-var-cp.exp?
gdb.mi/mi-var-cp.cc?

Its for variable objects, and for consistency.  The testsuite has the directory
gdb.cp and it's populated with *.cc files
