0d01eb54e7 More vector::iterator debug mode tests. Run by adding to OPTIONS -D_LIBCPP_DEBUG2=1.

f5f4684e71 Debug mode: learning to crawl. I need to set up some tests that actually test that the debug mode is working, but that won't cause problems when debug mode isn't on. This is my first prototype of such a test. It should call std::terminate() because it's comparing iterators from different containers. And std::terminate() is rigged up to exit normally. If debug mode fails, and doesn't call terminate, then the program asserts. The test is a no-op if _LIBCPP_DEBUG2 is not defined or is defined to be 0.

ae7bf9daac Marshall Clow found some divide-by-zero warnings with UBSan in rand's binomial_distribution test. This eliminates the divide-by-zeros and describes in comments the numerical difficulties the test is having. Each of the problematic tests are exploring edge cases of the distribution.

9976b5511a 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.

06d8bf6ce2 Test cleanup with respect to use of deprecated tmpnam function. Also Windows port for these tests to use _tempnam. The bulk of this patch was donated anonymously. I've tested it on OS X and accept responsibility for it. If I've broken anyone's platform by switching from tmpnam to mktemp for the generation of temporary file names, just let me know. Should be easy to fix in test/support/platform_support.h

707f318787 Change _LIBCPP_TYPE_VIS to use __type_visibility__(default) instead of __visibility__(default) when available. This change makes just the type_info visible so that types like vectors and strings can be used as exception objects across dylib boundaries even when hidden visibility is specified globally (at the command line), and yet this allows clients to hide the member functions of things like vector and string (with global visibility commands).

76aa2ef017 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.

1608b64881 [tests] Add back stdc macros I accidentally refactored out. 
- Patch by Michael van der Westhuizen:
--
r174404 accidentally removed stdc format, limit and constant macros from the Linux test runner logic.  This small patch re-adds the macros.

Making this change fixes the following tests on Linux:
 - depr/depr.c.headers/inttypes_h.pass.cpp
 - depr/depr.c.headers/stdint_h.pass.cpp
 - input.output/file.streams/c.files/cinttypes.pass.cpp
 - language.support/cstdint/cstdint.syn/cstdint.pass.cpp

fe14b970ac [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.
