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.

Quite a few libcxx tests seem to follow the format:
#if _LIBCPP_STD_VER > X
// Do test.
#else
// Empty test.
#endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.

Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.
This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

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.

Summary:
This patch does 2 main things:
1. Enable sized delete if the feature test macro `__cpp_sized_deallocation` is enabled.
2. Rework and cleanup all of the sized delete tests.
Test Plan:
The sized delete replacement tests are now split into 4 files:
1. sized_delete11.pass.cpp: Ensure overriding sized delete in C++11 has no effect.
2. sized_delete14.pass.cpp: Test overriding sized delete in C++14 and ensure it is called. This test fails on clang and GCC < 5.1.
3. size_delete_calls_unsized_delete_.pass.cpp: Test that the default sized delete calls unsized delete.
4. sized_delete_fsizeddeallocation.pass.cpp: Test overriding sized delete when -fsized-deallocation is passed. This test should pass on clang and GCC >= 5.1
I have also removed a lot of cruft from the old tests. They no longer replace the new handler and tests that it is called for bad allocations.
