a cv-qualifier rvalue reference to the type, e.g.,

  template <class _Tp> char  __test(const volatile typename remove_reference<_Tp>::type&&);

The use of this function signature rather than the more
straightforward one used in C++98/03 mode, e.g.,

  template <class _Tp> char  __test(_Tp);

is broken in two ways:

  1) An rvalue reference cannot bind to lvalues, so is_convertible<X&,
  X&>::value would be false. This breaks two of the unique_ptr tests
  on Clang and GCC >= 4.5. Prior GCC's seem to have allowed rvalue
  references to bind to lvalues, allowing this bug to slip in.

  2) By adding cv-qualifiers to the type we're converting to, we get
  some incorrect "true" results for, e.g., is_convertible<const X&, X&>::value.

LWG 1385 [FCD] tuple_cat should be a single variadic signature (http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#1385).  This issue is only in Ready status, meaning it is not official, but probably will be this March in Madrid.  It was tentatively accepted in Batavia with the previso that Bill and I didn't have any problems implementing it.  This is my part of that agreement.

After a long break to wait for the atomic spec to settle, this completes the library part of <atomic>.  It currently won't even parse as it depends on the existence of the intrinsics specified at http://libcxx.llvm.org/atomic_design_a.html.  Everything has been tested using fake intrinsics which have now been removed.  As the intrinsics come online, the ATOMIC_* macros will need to be adjusted to reflect which operations are lock-free.  These macros will probably need to be #ifdef'd for each supported platform.

Getting <atomic> warmed back up.  We have a hopefully more stable spec now.  And I believe the intrinsic spec at http://libcxx.llvm.org/atomic_design_a.html is still good.
