Eric Fiselier bd23d4daac Remove all usages of REQUIRES-ANY in the test suite.
Pending LIT changes are about to remove the REQUIRES-ANY keyword
in place of supporting boolean && and || within "REQUIRES". This
patch prepares libc++ for that change so that when applied
the bots don't lose their mind.

Eric Fiselier f9127593a9 Implement P0513R0 - "Poisoning the Hash"
Summary:
Exactly what the title says.

This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it.

See http://wg21.link/P0513R0 for more info.

If there are no comments in the next couple of days I'll commit this

Stephan T. Lavavej 3d26ee2921 [libcxx] [test] Fix MSVC warnings C4127 and C6326 about constants.
MSVC has compiler warnings C4127 "conditional expression is constant" (enabled
by /W4) and C6326 "Potential comparison of a constant with another constant"
(enabled by /analyze). They're potentially useful, although they're slightly
annoying to library devs who know what they're doing. In the latest version of
the compiler, C4127 is suppressed when the compiler sees simple tests like
"if (name_of_thing)", so extracting comparison expressions into named
constants is a workaround. At the same time, using std::integral_constant
avoids C6326, which doesn't look at template arguments.

test/std/containers/sequences/vector.bool/emplace.pass.cpp
Replace 1 == 1 with true, which is the same as far as the library is concerned.

Fixes D28837.

Stephan T. Lavavej 6d184d1fb1 [libcxx] [test] Don't ask whether Incomplete& can be assigned to.
This is the subject of an active NB comment. Regardless of what the Working
Paper currently says, asking this question is morally wrong, because the
answer can change when the type is completed. C1XX now detects such
precondition violations and complains about them; perhaps Clang should too.

Fixes D28591.

Eric Fiselier 38590b3845 Fix std::string assignment ambiguity from braced initializer lists.
When support for `basic_string_view` was added to string it also
added new assignment operators from `basic_string_view`. These caused
ambiguity when assigning from a braced initializer. This patch fixes
that regression by making the basic_string_view assignment operator
rank lower in overload resolution by making it a template.

Eric Fiselier 1cd196e7b4 Improve CMake and LIT support for Windows
This patch contains multiple cleanups and fixes to better support building on
Windows.

* [Test] Fix handling of library runtime search paths by correctly adding them
  to the PATH variable when running the tests.

* [Test] Don't explicitly force "--target=i686-pc-windows" when running the
  test suite. Clang++ seems to deduce the correct target.

* [Test] Fix `.sh.cpp` tests on Windows by properly escaping flags used in
  shell commands. Specifically windows style paths which included spaces
  were causing these tests to fail.

* [CMake] Add "vcruntime" to the list of supported C++ ABI libraries in CMake, and
  teach the test suite how to handle it. For now libc++ defaults to using
  "vcruntime" on Windows except when libc++abi is in tree; That is probably
  a bug and should be changed to always use vcruntime, at least for now.

* [Misc] Move the "c++-build" include directory to the libc++ binary dir
  instead of the top level project dir and rename it "c++build". This is just
  misc cleanup. Libc++ shouldn't be creating internal build files and directories
  at the top-level projects root.

* [Misc] Build type_info's destructor when building for MSVC. This is a temporary
  work around to prevent link errors until we have a proper type_info
  implementation.

Eric Fiselier cc1f65ca30 [libc++] [CMake] Link with /nodefaultlibs on Windows
Summary:
This patch attempts to fix the libc++ build/link so that it doesn't use an default C++ libraries on Windows.  This is needed to prevent linking to MSVC's STL library.

Additionally this patch changes libc++ so that it is always linked with the non-debug DLL's (e.g. `/MD`). This is needed so that the test suite can correctly link the same libraries without needing to know which configuration `c++.dll` was linked with.

Eric Fiselier 1e33f12a7c Use __is_identifier to detect Clang extensions instead of __has_extension.
When -pedantic-errors is specified `__has_extension(<feature>)` is always
false when it would otherwise be true. This causes C++03 <atomic> to break
along with other issues.

This patch avoids the above problem by using __is_identifier(...) instead since
it is not affected by -pedantic-errors. For example instead of checking for
__has_extension(c_atomics) we now check `!__is_identifier(_Atomic)`, which
is only true when _Atomic is not a keyword provided by the compiler.

This patch applies similar changes to the detection logic for __decltype and
__nullptr as well.

Note that it does not apply this change to the C++03
`static_assert` macro since -Wc11-extensions warnings generated by expanding
that macro will appear in user code, and will not be suppressed as part of a
system header.
