the conversions create unnecessary temporaries
int&& a = static_cast<A&&>(x).a;
int&& b = static_cast<B&&>(x).b;
std::cout<<"a="<<&a<<", b="<<&b<<std::endl;
shows they have the same address

The testcases use "target c++11" target selector. This selector is not known
on 4.6 and earler branches. The testcases fail as following on 4.6 branch [1]:
Running target unix

for " dg-do 2 run { target c++11 } "

I see the exact same failures with 4.5 branch on all targets I'm testing.
