JF Bastien b1ba015b9f libc++: support NaCl when building thread.cpp 
Summary: NaCl shouldn't include sysctl.h when trying to determine std:🧵:hardware_concurrency, it should instead use sysconf(_SC_NPROCESSORS_ONLN) through unistd.h. No test needs to be changed, since hardware_concurrency.pass.cpp already tests that std:🧵:hardware_concurrency > 0.

Test Plan: make check-libcxx

JF Bastien 57148cbcbd libc++: add NaCl and PNaCl support for std::random_device 
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).

Dan Albert 86b75a4057 Add better support for custom test runners. 
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:
https://android-review.googlesource.com/#/c/116022/

Eric Fiselier 1eb8220aff 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.

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.

Eric Fiselier 5aedca96d5 [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.
