More fixes: One of my fixes to type_traits earlier today was incorrect, so that is reverted. Recently clang appears to have tightened up its definition of is_convertible and that has caused some failures in [unordered_][multi]map. I've switched to using is_constructible to restablish the desired functionality in [unordered_][multi]map. Specifically, inserting rvalues of move-only types for the keys.

noexcept for <memory>. I've added a few extension noexcept to: allocator_traits<A>::deallocate, allocaate<T>::deallocate, return_temporary_buffer, and default_delete<T>::operator()(T*) const. My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default|

noexcept for <tuple>. And in the process learned that I had done it wrong for pair's swap. I needed to create an __is_nothrow_swappable<T>::value trait that was smart enought to answer false when __is_swappable<T>::value is false. Otherwise one gets compile-time errors when using pair or tuple of non-swappable types, even if you never try to swap the pair or tuple.

This is a simplified (and superior) implementation of __invoke, __invokable and __invoke_of. It is superior in that __invoke now handles reference qualified member functions whereas the previous implementation did not. And it simply has less infrastructure in its implementation. I'm still learning how to program in C++11 (and probably will be for a long time). This change does not impact the behavior we're seeing in http://llvm.org/bugs/show_bug.cgi?id=9975

I had a giant misunderstanding of what 'synchronizes with' meant in [futures.async]/p5. This invalidated the current design of async in <future>. This is a new design, based on my new understanding, which has been confirmed on the lwg mailing list. The summary is that ~future() (and ~shared_future()) will block when they are created from within async, and the thread hasn't finished yet. As part of this work I created two new type traits: __invokable<F, Args...>::value and __invoke_of<F, Args...>::type. These are what result_of<F(Args...)> wanted to be when it grew up, but never will be. __invoke_of is carefully crafted so that it can serve as its own enable_if (type doesn't exist if the signature isn't invokable). All of this work is C++11 only.

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.
