[Bug libstdc++/21772] exception safety testing

The std::array error seems indeed bogus: if I'm not wrong, it happens when
swapping arrays, and there are no  guarantees that the operation doesn't throw
for std::array, because it's requires to just swap the ranges, thus copy
construct and copy assign each array element.

Another thing I noticed, about basic_string, something seems inappropriate for
it in the framework, since the value_type must be a POD!
