This clears up the printing of a NestedNameSpecifier so a trailing '::' is not printed, unless it refers into the global scope. This fixes a bunch of diagnostics where the trailing :: was awkward. This also prints the NNS quoted consistenty. There is a drive-by improvement to error recovery, where now we print the actual type instead of `<dependent type>`. This will clear up further uses of NNS printing in further patches.
