Eric Fiselier 3fe611e508 Split thread test into two parts. Mark one as XFAIL with ASAN. 
The second part of the test checks that std::terminate is called when a running
thread is move assigned to. Calling std::terminate prevents some of the destructors
to be called and ASAN fires on this.

Eric Fiselier 83fb578e4e Add support for "fancy" pointers to promise and packaged_task. 
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.

Jonathan Roelofs b3fcc67f8f Allow libc++ to be built on systems without POSIX threads 
If you're crazy enough to want this sort of thing, then add
-D_LIBCPP_HAS_NO_THREADS to your CXXFLAGS and
--param=additiona_features=libcpp-has-no-threads to your lit commnad line.

David Majnemer 58a0a70fb2 Handle partial nanosleeps in this_thread::sleep_for 
Signals may result in nanosleep returning with only some of the
requested sleeping performed.

Utilize nanosleep's "time-remaining" out parameter to continue sleeping
when this occurs.

Justin Bogner ca14e2b132 Fix XFAIL condition from r208840 
The XFAILs in r208840 were too general. They were meant to only apply
to testing when use_system_lib was set.

Justin Bogner e077269764 Work around ABI differences due to LWG 2056 in tests 
When testing against the system library, there is a relatively minor
ABI breakage that the std::future_errc values have been changed to
avoid using zero. Update the tests that rely on the values being
consistent.

This is as straightforward as it sounds, a renamed from shared_mutex to
shared_timed_mutex.

be rebuilt.

Howard Hinnant 65a87ccdbf This is a start at making the libc++ test suite friendlier to the -fnoexceptions flag. Although this is not a complete solution, it does reduce the number of test failures on OS X from 467 to 128 on OS X when -fno-exceptions is enabled, and does not impact the number of failures at all when -fno-exceptions is not enabled. The bulk of this code was donated anonymously.

David Chisnall 8b6a4de64a Fix a bug in mutex_try_to_lock. This was previously trying to unlock a mutex that it didn't own, causing an assertion failure in mutex.cpp. The issue was that the unique_lock went out of scope, releasing the lock on m, then m.unlock() was called on an already-unlocked mutex. 
This change removes the spurious m.unlock() call.  

If this test was previously passing for anyone with assertions enabled, then they should investigate bugs in their pthread implementation, as pthread_unlock() should not return 0 if the mutex is currently unlocked.

Daniel Dunbar 577e696425 [tests] Increase a bunch of wait limits. 
- Basically I just ran the thread tests many many times on a busy machine and
   bumped the timeouts whenever I hit a test failure.

 - This is obviously subpar, but is the best I can do without the tests being
   rewritten to not depend on arbitrary timeouts.
