c2f0e465ca Overhaul and separate nullptr_t tests to pass with C++03. 
The standard requires that nullptr_t can be reinterpret_cast to an integral type
at least the size of nullptr_t. There is no way to emulate this conversion in
the C++03 nullptr_t implementation. The test for this conversion has been moved
to a new test and marked XFAIL with c++03.

This recommits what was originally r222296.

221907d782 Cleanup quick_exit tests and get them passing in C++03. 
Wrap the original test in _LIBCPP_HAS_QUICK_EXIT so it only runs when we have
quick_exit and add two new tests that check that when _LIBCPP_HAS_QUICK_EXIT
is not defined then no definition of std::at_quick_exit or std::quick_exit are
available.

8e2855ce0b [libcxx] Refactor CMakeLists.txt handling of compile and link flags to suppress warnings. 
Summary:
Currently we have 5 variables that are used to specify options for building libcxx
1. `LIBCXX_CXX_FEATURE_FLAGS`
2. `LIBCXX_CXX_WARNING_FLAGS`
3. `LIBCXX_CXX_REQUIRED_FLAGS`
4. `compile_flags` (in libcxx/lib)
5. `link_flags` (in libcxx/lib)

The first three all get put into `CMAKE_CXX_FLAGS`. 
This changes the way flags are handled by only using 3 different options:

1. `LIBCXX_CXX_FLAGS` - general compile and link flags.
2. `LIBCXX_COMPILE_FLAGS` - compile only flags.
3. `LIBCXX_LINK_FLAGS` - link only flags.

This patch also removes the warning about `-nostdinc++` being unused during linking.

0364baca04 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

50ada3a8f7 [libcxx] Fix memory leak in strstream tests. 
Summary: The strstream function `str()` sets `freeze(true)`. When `freeze` is true the destructor is not allowed to free any dynamically allocated memory. The memory leak causes ASAN to fail on these tests. To ensure memory is deallocated `strstream.freeze(false)` is called at the end of the tests.

1c3b15d339 Split string capacity test into two parts and mark one part as UNSUPPORTED when using sanitizers. 
The test is split such that:
- max_size.pass.cpp tests that string::resize() fails to allocator for max_size
  and max_size -1
- over_max_size.pass.cpp tests that string::resize() throws a length error for
  max_size + 1

The test was split into two because max_size.pass.cpp cannot pass with 
sanitizers but over_max_size.pass.cpp can.

71915c132a Mark more tests as UNSUPPORTED with ASAN and MSAN. 
These tests fail for 2 reasons when using ASAN and MSAN.
1. If allocator_may_return_null=0 they will fail because null is returned
   or an exception is thrown.
2. When allocator_may_return_null=1 the new_handler is still not called. This
   results in an assertion failures.
