4e3e15ad99 [libc++] Remove various C++03 feature test macros
Summary:
Libc++ still uses per-feature configuration macros when configuring for C++11. However libc++ requires a feature-complete C++11 compiler so there is no reason to check individual features. This patch starts the process of removing the feature specific macros and replacing their usage with `_LIBCPP_CXX03_LANG`.

This patch removes the __config macros:

* _LIBCPP_HAS_NO_TRAILING_RETURN
* _LIBCPP_HAS_NO_TEMPLATE_ALIASES
* _LIBCPP_HAS_NO_ADVANCED_SFINAE
* _LIBCPP_HAS_NO_DEFAULT_FUNCTION_TEMPLATE_ARGS
* _LIBCPP_HAS_NO_STATIC_ASSERT

As a drive I also changed our C++03 static_assert to use _Static_assert if available.

I plan to commit this without review if nobody voices an objection.

040945b81f [libcxx] Introduce an externally-threaded libc++ variant.
This patch further decouples libc++ from pthread, allowing libc++ to be built
against other threading systems. There are two main use cases:

- Building libc++ against a thread library other than pthreads.

- Building libc++ with an "external" thread API, allowing a separate library to
  provide the implementation of that API.

The two use cases are quite similar, the second one being sligtly more
de-coupled than the first. The cmake option LIBCXX_HAS_EXTERNAL_THREAD_API
enables both kinds of builds. One needs to place an <__external_threading>
header file containing an implementation of the "libc++ thread API" declared
in the <__threading_support> header.

For the second use case, the implementation of the libc++ thread API can
delegate to a custom "external" thread API where the implementation of this
external API is provided in a seperate library. This mechanism allows toolchain
vendors to distribute a build of libc++ with a custom thread-porting-layer API
(which is the "external" API above), platform vendors (recipients of the
toolchain/libc++) are then required to provide their implementation of this API
to be linked with (end-user) C++ programs.

Note that the second use case still requires establishing the basic types that
get passed between the external thread library and the libc++ library
(e.g. __libcpp_mutex_t). These cannot be opaque pointer types (libc++ sources
won't compile otherwise). It should also be noted that the second use case can
have a slight performance penalty; as all the thread constructs need to cross a
library boundary through an additional function call.

When the header <__external_threading> is omitted, libc++ is built with the
"libc++ thread API" (declared in <__threading_support>) as the "external" thread
API (basic types are pthread based). An implementation (pthread based) of this
API is provided in test/support/external_threads.cpp, which is built into a
separate DSO and linked in when running the libc++ test suite. A test run
therefore demonstrates the second use case (less the intermediate custom API).

7f735c31c0 Fix PR30202 - notify_all_at_thread_exit seg faults if run from a raw pthread context.
Summary:
This patch allows threads not created using `std::thread` to use `std::notify_all_at_thread_exit` by ensuring the TL state has been initialized within `std::notify_all_at_thread_exit`.

Additionally this patch "fixes" a potential oddity in `__thread_local_pointer::reset(pointer)`, which would previously delete the old thread local data. However there should *never* be old thread local data because pthread *should* null it out on thread exit. Unfortunately it's possible that pthread failed to do this according to the spec:


> 
> Upon key creation, the value NULL shall be associated with the new key in all active threads. Upon thread creation, the value NULL shall be associated with all defined keys in the new thread.
> 
> An optional destructor function may be associated with each key value. At thread exit, if a key value has a non-NULL destructor pointer, and the thread has a non-NULL value associated with that key, the value of the key is set to NULL, and then the function pointed to is called with the previously associated value as its sole argument. The order of destructor calls is unspecified if more than one destructor exists for a thread when it exits.
> 
> If, after all the destructors have been called for all non-NULL values with associated destructors, there are still some non-NULL values with associated destructors, then the process is repeated. If, after at least {PTHREAD_DESTRUCTOR_ITERATIONS} iterations of destructor calls for outstanding non-NULL values, there are still some non-NULL values with associated destructors, implementations may stop calling destructors, or they may continue calling destructors until no non-NULL values with associated destructors exist, even though this might result in an infinite loop.

However if pthread fails to delete the value it is probably incorrect for us to do it. Destroying the value performs all of the "at thread exit" actions registered with it but we are way past "at thread exit".

e0620e29a5 [CMake] Be more consistent about naming targets and components
Summary:
The point of this patch is to have a consistent convention for naming build, check and install targets so that the targets can be constructed from the project name.

This change renames a bunch of CMake components and targets from libcxx to cxx. For each renamed target I've added a convenience target that matches the old target name and depends on the new target. This will preserve function of the old targets so that the change doesn't break the world. We can evaluate if it is worth removing the extra targets later.

98983c06c5 libcxx: Fix libcxx tests on aarch64 with libunwind
Some tests uses 'long double' to/from conversions and for some targets
they are provided by compiler runtime (either compiler-rt or libgcc).
However when building libcxx with linunwinder current test configuration
at target_info.py do not include the required libraries, as:

  not llvm_unwinder:
    "-lc++" "-lm" "-lgcc_s" "-lgcc" "-lpthread" "-lc" "-lgcc_s" "-lgcc"

  llvm_unwinder
    "-lc++" "-lm" "-lpthread" "-lc" "-lunwind" "-ldl"

This causes some tests build issues with missing symbols on aarch64,
for instance, where 'long double' is a binary float with 128-bits with
mostly of internal operations being provided by software routines.

This patch changes how to define the default linker flags with libunwinder by
adding libgcc regardless.

I checked and aarch64 and x86_64 with libcxx and libunwind (with and without
LIBCXXABI_USE_LLVM_UNWINDER).

8c22696675 [CMake] Get libcxx building under LLVM/runtimes
Summary:
The new LLVM runtimes build directory requires some basic conventions across the runtime projects. These changes make libcxx build under the runtimes subdirectory. The general idea of the changes is that the runtimes subdirectory requires some conventions to be consistent across runtime projects.

I expect to have a few more small patches that build on this to tie up check targets and other things useful in development workflows.

Summary of changes in this patch:

* Renamed variable LLVM_CONFIG -> LLVM_CONFIG_PATH
* Renamed variable LIBCXX_BUILT_STANDALONE -> LIBCXX_STANDALONE_BUILD
* Add an include of AddLLVM in the tests subdirectory for add_lit_testsuite.

ea714e73a6 libcxx: Fix path.compare.pass expected result
The expected 'filesystem::path::compare' result states that for different
path only result sign contains the information about passed arguments
(not its integer value).  This is due it uses the output of other compare
functions (basic_string_view and char_traits) without further handling and
char_traits uses memcmp for final buffer comparison.

However for GLIBC on AArch64 the code:

  int ret = memcmp ("b/a/c", "a/b/c", 1);

Results in '64' where for x86_64 it results in '1'.

This patch fixes the expected 'filesystem::path::compare' by normalizing
all the results before assert comparison.

e739d54f86 [libcxx] Add std::any
Summary:
This patch adds std::any by moving/adapting <experimental/any>.

This patch also implements the std::any parts of p0032r3 (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0032r3.pdf)
and LWG 2509 (http://cplusplus.github.io/LWG/lwg-defects.html#2509).

I plan to push it in a day or two if there are no comments.

2d08bc9a9f Implement LWG 2148: Make non-enum default hash specialization well-formed
Summary:
This patch removes the static_assert for non-enum types in the primary hash template. Instead non-enum types create a hash<T> specialization that is not constructible nor callable.

9639abed2e Fix copy/move constructor annotation for the uses-allocator test types.
Previously the copy/move constructors of the test types did not
properly set the arg_id to T const& or T&& respectivly.

7f6e8e2141 [libcxx] Add "flag" default arg: basic_regex ptr_size_flag ctor
Summary:
The synopsis in C++11 subclause 28.8 [re.regex] has:
```
basic_regex(const charT* p, size_t len,
            flag_type f = regex_constants::ECMAScript);
```

The default argument is added to libc++ by this change.
