The approach is rather straightforward and the work for the most part consisted of mimicking the behavior for regular references. In gdbtypes.c, several helper functions were introduced and some parameterized by the reference kind to simplify the access to reference type objects API. The only interesting part is the addition of overloading resolution rules with regard to rvalue references. All of the cases introduced in 13.3.3.1.4 and 13.3.3.2 were accounted for at the beginning of rank_one_type(). With this patch it is now also possible to fix the evaluation of decltype, which should return a plain type object, an lvalue reference or an rvalue reference depending on a type category of the type of its operand. However, this would require introduction of the type catyegory notion to gdb, which I think only needs adding a new constant to lval_type and propagating the type category through different parts of an expression in gdb/valops.c. I'm willing to do this if this patchset turns out to be OK.
