Using the system default 'ar' might not be the right choice when
cross compiling.
Don't prepend the ar options by a dash, not all ar implementations
support that (llvm-ar doesn't).
Also pass the 's' option when creating the merged library, to create
an index.

This patch fixes llvm.org/PR34298. Previously libc++ incorrectly evaluated
the __invokable trait via the converting constructor `function(Tp)` [with Tp = std::function]
whenever the copy constructor or copy assignment operator
was required. This patch further constrains that constructor to short
circut before evaluating the troublesome SFINAE when `Tp` matches
std::function.
The original patch is from Alex Lorenz.

This reverts commit r312890 because the test case fails to compile for
older versions of Clang that reject initializing a const object without
a user defined constructor.
Since this patch should go into 5.0.1, I want to keep it an atomic change,
and will re-commit it with a fixed test case.

_strftime_l is only available in the numbered msvcrt versions
(starting from msvcr80.dll). In the default configuration, mingw
targets the unversioned msvcrt.dll - and there, _strftime_l is
not available (not even on windows 10).
If __MSVCRT_VERSION__ is set to a higher value (indicating a
non-default target and wanting to link to msvcrXX.dll), use the
correct function.

This is essential when building with -nodefaultlibs.
This is similar to what already is done in libcxxabi in SVN r302760.

* Update specification text from N4387
* Delete not_brace_initializable.fail.cpp: it's redundant with nullopt_t.fail.cpp
* is_empty<T> implies is_class<T>
* is_literal is deprecated; directly verify that we can create a nullopt_t in a constexpr context

Replace unary_function/binary_function inheritance with typedefs.

Mark these tests as requiring 98/03/11/14 because 17 removed unary_function/binary_function.

test/std/thread/futures/futures.task/futures.task.nonmembers/uses_allocator.pass.cpp
Mark these tests as requiring 11/14 because 17 removed packaged_task allocator support.
test/std/utilities/function.objects/func.wrap/func.wrap.func/derive_from.pass.cpp
This test doesn't need to be skipped in C++17 mode. Only the construction of
std::function from an allocator needs to be skipped in C++17 mode.

When testing these reference_wrapper features, unary_function inheritance is totally irrelevant.
test/std/utilities/function.objects/refwrap/weak_result.pass.cpp
Define and use my_unary_function/my_binary_function to test the weak result type machinery
(which is still present in C++17, although deprecated).
test/support/msvc_stdlib_force_include.hpp
Now we can test C++17 strictly, without enabling removed features.
Fixes D36503.

This improves readability and (theoretically) improves portability,
as _Ugly names are reserved.
This performs additional de-uglification, so all of these tests
follow the example of iterator.traits/empty.pass.cpp.

libc++'s inline namespace can change depending on the ABI version.
Instead of hardcoding __1 in the manual Microsoft ABI manglings for the
iostream globals, stringify _LIBCPP_NAMESPACE and use that instead, to
work across all ABI versions.

This function template is referenced inside class basic_string as a
friend function. The extern template declaration needs to be above that
friend declaration to actually take effect.
This is important because this function was marked as exported in
r307966, so without the extern template taking effect, it can leak into
other DSOs as a visible symbol.

This makes them consistent (many comments already used uppercase).
The special REQUIRES, UNSUPPORTED, and XFAIL comments are excluded from this change.
