Summary:
This patch adds a lit option to enable color diagnostics when either `--param=color_diagnostics` is passed to LIT or `LIBCXX_COLOR_DIAGNOSTICS` is present in the environment.
My only concern with this patch is that GCC and Clang take different flags and that only GCC 4.9 and greater support `-fdiagnostics-color=always`
Does anybody have objections to this going in?

Summary:
This patch introduces some black magic to detect const and volatile qualified function types such as `void () const`.
The patch works in the following way:
We first rule out any type that satisfies on of the following. These restrictions are important so that the test below works properly.
* `is_class<_Tp>::value`
* `is_union<_Tp>::value`
* `is_void<_Tp>::value`
* `is_reference<_Tp>::value`
* `__is_nullptr_t<_Tp>::value`
If none of the above is true we perform overload resolution on `__source<_Tp>(0)` to determine the return type.
* If `_Tp&` is well-formed we select `_Tp& __source(int)`. `_Tp&` is only ill formed for cv void types and cv/ref qualified function types.
* Otherwise we select `__dummy_type __source(...)`. Since we know `_Tp` cannot be void then it must be a function type.
let `R` be the returned from `__source<_Tp>(0)`.
We perform overload resolution on `__test<_Tp>(R)`.
* If `R` is `__dummy_type` we call `true_type __test(__dummy_type)`.
* if `R` is `_Tp&` and `_Tp&` decays to `_Tp*` we call `true_type __test(_Tp*)`. Only references to function types decay to a pointer of the same type.
* In all other cases we call `false_type __test(...)`.
`__source<_Tp>(0)` will try and form `_Tp&` in the return type. if `_Tp&` is not well formed the return type of `__source<_Tp>(0)` will be dummy type. `_Tp&` is only ill-formed for cv/ref qualified function types (and void which is dealt with elsewhere).

Checking errno without first checking that the call failed means that
if some other call prior to mkstemp failed with EINVAL prior to this,
the assert would fire even if mkstemp succeeded. If something failed
with EEXIST, it would go in to an infinite loop.

Summary:
Hello Howard,
While running the libc++ tests on our ARM boards, we encounter sporadic failures of the two tests:
test/std/thread/futures/futures.shared_future/wait_until.pass.cpp
test/std/thread/futures/futures.unique_future/wait_until.pass.cpp
The worker thread might not finish yet when the main thread checks its result.
I filed the bug 21998 for this case: http://llvm.org/bugs/show_bug.cgi?id=21998
Would you be able to review this please?
Thank you.
Oleg

`__invoke_void_return_wrapper` is needed to properly handle calling a function that returns a value but where the std::function return type is void. Without this '-Wsystem-headers' will cause `function::operator()(...)` to not compile.

Summary:
The requirement on the `Size` type passed to *_n algorithms is that it is convertible to an integral type. This means we can't use a variable of type `Size` directly. Instead we need to convert it to an integral type first. The problem is finding out what integral type to convert it to. `__convert_to_integral` figures out what integral type to convert it to and performs the conversion, It also promotes the resulting integral type so that it is at least as big as an integer. `__convert_to_integral` also has a special case for converting enums. This should only work on non-scoped enumerations because it does not apply an explicit conversion from the enum to its underlying type.

Before this patch, the CMake build assumed LIT_EXECUTABLE pointed
to a Python script, not an executable. If you were to pass in an
executable, such as the result of py2exe on lit.py, the build would
fall over.
With this patch, the CMake build assumes LIT_EXECUTABLE is an
executable. You can continue setting it to lit.py, but it will
now use its shebang to find a Python interpreter.

he following snippet doesn't build when using gcc and libc++:
#include <string>
void f(const std::string& s) { s.begin(); }
#include <vector>
void AppendTo(const std::vector<char>& v) { v.begin(); }
The problem is that __wrap_iter has a private constructor. It lists vector<>
and basic_string<> as friends, but gcc seems to ignore this for vector<> for
some reason. Declaring vector before the friend declaration in __wrap_iter is
enough to work around this problem, so do that. With this patch, I'm able to
build chromium/android with libc++. Without it, two translation units fail to
build. (iosfwd already provides a forward declaration of basic_string.)
As far as I can tell, this is due to a gcc bug, which I filed as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64816.
Fixes PR22355.

Summary:
This patch allows the use of LIT's ShTest format in the libc++ test suite. ShTests have the suffix '.sh.cpp'. It also introduces a series of other changes. These changes are:
- More functionality including parsing test metadata has been moved into LIT.
- LibcxxTestFormat now supports multi-part suffixes.
- the `CXXCompiler` functionality has been used to shrink the size of LibcxxTestFormat.
- The recursive loading of the site config has been turned into `libcxx.test.config.loadSiteConfig` so it can be used with libc++abi.
- Temporary files are now created in the build directory of libc++. This follows how it is down in ShTest.
- `not.py` was added as a utility executable that mirrors the functionality of LLVM's `not` executable.
- The first ShTest test was added under test/libcxx/double_include.sh.cpp
