Fix gnuv3_pass_by_reference to lookup copy c-tors with qualified args.
Before this, a copy constructor declared as in the following snippet was
not being treated as a copy constructor.
class A
{
public:
A (A &); // OK.
A (const A &); // Not being treated as a copy constructor because of the
// 'const' qualifier.
};

with qualified args.
