Summary:
This adds the <experimental/type_traits> (minus invocation traits). Mostly just the `_v` traits.

Summary:
In order to get the bots running quicker I would like to be able to use ccache
with the test suite. This patch adds support for running the test suite using
ccache. To use ccache pass `--param=use_ccache=true` when running the test suite.
ccache will not cache any command that invokes ld, so the build step needs to be
split into two separate compile commands. The cost of splitting the build step
into two parts when not using ccache seems to be minimal. On my machine I saw a
difference of ~5 seconds on a 5 minute test suite run.
A full test suite run with ccache generates about 250MB of cached data.
I recorded the following times for running the test suite in the following configurations:
- no ccache: 340s
- initial ccache run: 380s
- rerun with ccache (no changes): 53s.
- rerun with ccache (<string> changed): 80s
- rerun with ccache (<cmath> changed): 169s
- rerun with ccache (<valarray> changed): 69s

Summary:
This patch probes the cxx compiler used during testing by getting it to dump its predefined macros. Based on the value of these macros the compiler name and compiler name + version are added to the available features.
There are three compiler names:
- `clang`
- `apple-clang`
- `gcc`.
The available features added are equivalent to:
- `'%s' % compiler_name`
- `'%s-%s.%s' % compiler_name, major_version, minor_version`
This information can be used to XFAIL tests on different compilers / versions.

Currently hacks must be used in to configure and build libc++ without threads
when using CMake. This patch adds CMake options to enable/disable building with
threads and a monotonic clock.
This patch also propagates the configuration information to lit so the tests
are properly configured as well.

Summary:
The NaCl sandbox doesn't allow opening files under /dev, but it offers an API which provides the same capabilities. This is the same random device emulation that nacl_io performs for POSIX support, but nacl_io is an optional library so libc++ can't assume that device emulation will be performed. Note that NaCl only supports /dev/urandom, not /dev/random.
This patch also cleans up some of the preprocessor #endif, and fixes the test for Win32 (it accepts any token, and would therefore never throw regardless of the token provided).

Summary:
I finally got around to merging the many, many changes to lit.cfg into
Android's libc++. This patch makes it simpler to actually use a custom
configuration and test format.
First, I've factored out _build, _run, and _clean methods from
_execute_test, since these are the likely parts that will need to be
overridden. This is likely a first step in the work jroelofs has been
doing with improving cross-compiling test execution.
Second, I've added a `configuration_variant` to the config. This
entry, if present, is a string that forms the prefix of the class that
is to be used to configure the test runner. For example, Android sets
`config.configuration_variant = 'Android'`, and this causes an object
of type `AndroidConfiguration` to be constructed.
As an example of how this will be used, see:

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.

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.
