 Ah great! I had completely missed it...

I have reviewed the patch then, and taken the liberty of pasting the
paragraph of the Standard that specifies this just above the little piece of
code. I have also added the tests to `destructor.cpp`.

I have ordered the test so that  hasAttr<FinalAttr>  is the last condition,
in order to economize the calls (I suppose it's less costly than looking up
the destructor).

Since this means that I now specifies -std=c++0x on the command line (for
final), I would understand if it should only be activated conditionally or
if the test should be split.
