[NFC] Rename _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS
...
The name _LIBCPP_TYPE_VIS_ONLY is no longer accurate because both
_LIBCPP_TYPE_VIS and _LIBCPP_TYPE_VIS_ONLY expand to
__attribute__((__type_visibility__)) with Clang. The only remaining difference
is that _LIBCPP_TYPE_VIS_ONLY can be applied to templates whereas
_LIBCPP_TYPE_VIS cannot (due to dllimport/dllexport not being allowed on
templates).
This patch renames _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS.

Cleanup non-standard tests as reported by STL@microsoft.com. NFC.

This patch addresses the following issues in the test suite:
1. Move "std::bad_array_length" test from std/ to libcxx/ test directory
since the feature is not a part of the standard.
2. Rename "futures.tas" test directory to "futures.task" since that is the
correct stable name.
3. Move tests for "packaged_task<T>::result_type" from std/ to libcxx/
test directory since the typedef is a libc++ extension.

Cleanup: move visibility/linkage attributes to the first declaration.

This change moves visibility attributes from out-of-class method
definitions to in-class declaration. This is needed for a switch to
attribute((internal_linkage)) (see http://reviews.llvm.org/D13925 )
which can only appear on the first declaration.
This change does not touch istream/ostream/streambuf. They are
handled separately in http://reviews.llvm.org/D14409 .

Summary:
This patch is very closely related to D4859. Please see http://reviews.llvm.org/D4859 for more information.
This patch adds support for "fancy" pointers and allocators to promise and packaged_task. The changes made to support this are exactly the same as in D4859.
Test Plan: "fancy" pointer tests were added to each constructor affected by the change.

Apple LWG 2067: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3318.html#2067 . This is the only actionable change that has been made to the C++ draft since C++11. In general it has not been decided exactly how libc++ will track changes made to C++11. New features and design changes will probably be #ifdef'd, especially if they are not backwards compatible. Defects and 'dumb mistakes' are more likely to just be put in. Decisions on telling one from the other will be made on a case by case basis.

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|

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.
