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).

r318862 added a fix for 0-termination input array in case of an error. Previous
libcxx versions don't have the fix and corresponding tests should be failing.

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
(using charT()) into the next successive location of the array.

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
d:\contest\gl0qojfu.5pe\src\qa\vc\libs\libcxx\upstream\test\std\containers\sequences\vector.bool\size.pass.cpp(33) : warning C6326: Potential comparison of a constant with another constant.

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.

Summary:
In the CHERI clang compiler __output and __input are keywords and therefore
we can't compile libc++ with our compiler.

The commit r300140 changed the implementation of compressed_pair, but didn't add
_LIBCPP_INLINE_VISIBILITY to the constructors and get members of the
compressed_pair_elem class. This patch adds the visibility annotation.
I didn't find a way to test this change with libc++ regression tests.
