Summary:
Introduce a new form of `result_of` without function type encoding.
Rename and split `is_callable/is_nothrow_callable` into `is_invocable/is_nothrow_invocable/is_invocable_r/is_nothrow_invocable_r` (and associated types accordingly)
Change function type encoding of previous `is_callable/is_nothrow_callable` traits to conventional template type parameter lists.

Currently libc++ defines operator== and operator!= as friend functions in the
definition of the istream_iterator class template. Such definition has a subtle
difference from an out-of-line definition required by the C++ Standard: these
functions can only be found by argument-dependent lookup, but not by qualified
lookup.
This patch changes the definition, so that it conforms to the C++ Standard and
adds a check involving qualified lookup to the test suite.
Patch contributed by Mikhail Maltsev.

These buildbots are using the deprecated target name install-libcxx-headers
instead of the more up to date install-cxx-headers, so I need to add an
install-libcxx-headers-stripped target to satisfy them.

LLVM is gaining install-*-stripped targets to perform stripped installs,
and in order for this to be useful for install-distribution, all
potential distribution components should have stripped installation
targets. LLVM has a function to create these install targets, but since
we can't use LLVM CMake functions in libc++, let's do it manually.

The MSVC driver and clang do not link against the C++ runtime
explicitly. Instead, they rely on the auto-linking via the pragma
(through `use_ansi.h`) to link against the correct version of the C++
runtime. Attempt to do something similar here so that linking real C++
code on Windows does not require the user to explicitly specify
`c++.lib` when using libc++ as a C++ runtime on windows.

Summary:
We want to automatically copy the appropriate mailing list
for review requests to the libc++ repository.
For context, see the proposal and discussion here:

Similar to D40179, I set up a new Diffusion repository with callsign
"CXX" for libc++:
https://reviews.llvm.org/source/libcxx/
This explicitly updates libcxx's .arcconfig to point to the new
CXX repository in Diffusion, which will let us use Herald rule H268.

Previously, the install command for the cxxabi headers specified
the wrong component, and therefore they were not being included
in the install-cxx command.
This patch corrects the component name.

Fix the problem PR31516 with setting locale on Windows by wrapping
_locale_t with a pointer-like class.
Reduces 74 test failures in std/localization test suite to 47 test
failures (on llvm clang, Visual Studio 2015). Number of test failures
doesn't depend on the platform (x86 or x64).

It covers the cases when the sentry object returns false and when an exception
was thrown. Corresponding standard paragraph is C++14 [istream.unformatted]p21:
In any case, if n is greater than zero, it then stores a null character

In a17cd7c641 Marshall added assert(true) to the vector<bool>::size tests, which break on C1XX:
D:\Contest\gl0qojfu.5pe\src\qa\vc\libs\libcxx\upstream\test\std\containers\sequences\vector.bool\size.pass.cpp(62): error C2220: warning treated as error - no 'object' file generated

The corresponding test for vector::size asserts assert(c.size() == 3);, so I changed it to do that here.

One can't replace vsscanf(_l) with a sscanf(_l) that doesn't
take a va_list.
This has been untouched since it was added in SVN r140728, so
apparently it hasn't been used since. One reason for this mistake
originally might have been that there was no _vsscanf_l until MSVC
2015.
Since it's unused, just remove this define.

The non-const data() member of std::string is only exposed
in C++17 and beyond. However std::string is externally instantiated
and so the member function needs to be exposed to be externally instantiated.
On Linux and OS X this shouldn't cause a problem, because
_LIBCPP_INLINE_VISIBILITY ensures the symbol is always inlined.
However on Windows, the symbol gets marked dllimport, but
there is no definition to import, causing link errors.

Summary:
Currently `std::variant` always uses an unsigned int to store the variant index. However this isn't nessesary and causes `std::variant` to be larger than it needs to be in most cases.
This patch changes the index type to be `unsigned char` when possible, and `unsigned short` or `unsigned int` otherwise, depending on the size (Although it's questionable if it's even possible to create a variant with 65535 elements.
Unfortunately this change is an ABI break, and as such is only enabled in ABI v2.
