std::packaged_task requires variadic templates and is #ifdef out in C++03.
This patch silences the tests in C++03. This patch also rewrites the .fail.cpp tests so that they use clang verify.

Summary:
This patch attempts to fix the last 3 TSAN failures on the libc++ bot (http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-tsan/builds/143). This patch also adds a `Atomic` test type that can be used where `<atomic>` cannot.
`wait.exception.pass.cpp` and `wait_for.exception.pass.cpp` were failing because the test replaced `std::terminate` with `std::exit`. `std::exit` would asynchronously run the TLS and static destructors and this would cause a race condition. See PR22606 and D8802 for more details.
This is fixed by using `_Exit` to prevent cleanup.
`notify_all_at_thread_exit.pass.cpp` exercises the same race condition but for different reasons. I fixed this test by manually joining the thread before beginning program termination.

Summary:
This patch fixes __not_null's detection of nullptr by breaking it down into 4 cases.
1. `__not_null(Tp const&)`: Default case. Tp is not null.
2. `__not_null(Tp* __ptr);` Case for pointers to functions.
3. `__not_null(_Ret _Class::* __ptr);` Case for pointers to members.
4. `__not_null(function<Tp> const&);`: Cases for other std::functions.

When I was refactoring the unique_ptr.single.ctor tests I added a test
deleter, 'NCDeleter', to deleter.h. Other tests that include deleter.h
redefine the NCDeleter type causing test failures.

One of the last sections of tests that still fail in C++03 are the unique_ptr
tests. This patch begins cleaning up the tests and fixing C++03 failures.
The main changes of this patch:
- The "Deleter" type in "deleter.h" tried to be "move-only" in C++03. However
the move simulation no longer works (see "__rv"). "Deleter" is now copy
constructible in C++03. However copying "Deleter" will "move" the test value
instead of copying it.
- Reduce the unique.ptr.single.ctor tests files from ~25 to 4. There is no
reason the tests were split through so many files.

Before I start trying to fix __invoke in C++03 it needs better test coverage.
This patch adds a large amount of tests for __invoke.

<__functional_03> provides the C++03 definitions for std::memfun and
std::function. However the interaction between <functional> and <__functional_03>
is ugly and duplicates code needlessly. This patch cleans up how the two
headers work together.
The major changes are:
- Provide placeholders, is_bind_expression and is_placeholder in <functional>
for both C++03 and C++11.
- Provide bad_function_call, function fwd decl,
__maybe_derive_from_unary_function and __maybe_derive_from_binary_function
in <functional> for both C++03 and C++11.
- Move the <__functional_03> include to the bottom of <functional>. This makes
it easier to see how <__functional_03> interacts with <functional>
- Remove a commented out implementation of bind in C++03. It's never going
to get implemented.
- Mark almost all std::bind tests as unsupported in C++03. std::is_placeholder
works in C++03 and C++11. std::is_bind_expression is provided in C++03 but
always returns false.

Summary: This patch adds proper guards to the is_destructible tests depending on the standard version so that they pass in c++03.

Automatically enable clang verify whenever the '-verify-ignore-unexpected' flag
is supported.
Failure tests are run using verify if they contain one or more "expected-*"
diagnostics tags. Otherwise they are run normally.

One of the aspects of CloudABI is that it aims to help you write code
that is thread-safe out of the box. This is very important if you want
to write libraries that are easy to reuse. For CloudABI we decided to
not provide the thread-unsafe functions. So far this is working out
pretty well, as thread-unsafety issues are detected really early on.
The following patch adds a knob to libc++,
_LIBCPP_HAS_NO_THREAD_UNSAFE_C_FUNCTIONS, that can be set to disable
thread-unsafe functions that can easily be avoided in practice. The
following functions are not thread-safe:
- <clocale>: locale handles should be preferred over setlocale().
- <cstdlib>: mbrlen(), mbrtowc() and wcrtomb() should be preferred over
their non-restartable counterparts.
- <ctime>: asctime(), ctime(), gmtime() and localtime() are not
thread-safe. The first two are also deprecated by POSIX.
