Fix some wrong-code bugs in implicitly-defined assignment operators:
- In C++11, perform overload resolution over all assignment operators, rather than just looking for copy/move assignment operators.
- Clean up after temporaries produced by operator= immediately, rather than accumulating them until the end of the function.
