091c5ace78 Reverted previous fix to is_convertible as it caused more problems than it fixed. But this reverted fix will only matter for non-clang compilers. Installed __is_convertible_to for clang.

497ac97247 Inline namespaces are always available in Clang. Rely on that without
testing via __has_feature, since __has_feature for C++0x features no
longer evaluates true in C++98/03 mode.

Also, eliminate the redundant using directive. Inline namespaces make
their members visible in the enclosing namespace automatically.

aab015a929 Teach move_iterator that rvalue references cannot bind to non-function
lvalues, nor can one take the address of an xvalue, by adding
appropriate static_cast's (in the first case) and a temporary (in the
second case).

5ea2e37c08 Remove an (incorrect) compiler workaround in the __mu function. The
workaround relied on rvalue references binding to non-function
lvalues, while the original formulation (with std::forward) does the
right thing.

6c669943b3 An rvalue reference cannot bind to an lvalue, so static_cast the
result of the __tuple_leaf::get() call to an rvalue reference when
returning from tuple's get().

f9e1c7e367 Eliminate the C++0x-only is_convertible testing function that accepts
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.

0e1493ec5e 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.

770d1c4ea7 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.
