d74dee9255 Recommit r243503 "[libcxx] Cleanup CMake configuration and integrate with LLVM"
This change was reverted in r243550 because it broke clang-format builds
(see PR24306).

This patch recommits a fixed version of the original.

91eeba8d26 [libcxx] Cleanup CMake configuration and integrate with LLVM
Summary:
This patch contains the following changes:

1. Require that libc++ can find a LLVM source directory. This is done the same way as `libc++abi` currently does.
2. Cleanup ugly configuration code in CMakeLists.txt by using `add_flags`, `add_flags_if`, and `add_flags_if_supported` macros.

The goals for this patch are:

1. Help libc++ be more consistent with how LLVM handles CMake options (see PR23670 PR23671).
2. Make it easier to use sanitizers using the `LLVM_USE_SANITIZER` option.
3. Make libc++'s CMakeLists.txt file easier to understand and change.
4. Move towards allowing libc++ to create Sphinx documentation (see http://efcs.ca/libcxx-docs). 
5. Move towards allowing  libc++ to use other LLVM utilities such as `not` and `FileCheck`.

bfb46e486d Cleanup C++03 __invoke for Bullets 3 and 4.
The key changes in this patch are:

1. Remove the zero-argument overload in mem_fn. A member function must always
   be invoked with at least one argument, the class instance. The zero-argument
   operator()() in mem_fn would cause mem_fn to fail to compile when because
   the call to '__invoke(pm)' is not well formed.

2. Prevent evaluation of '__apply_cv<Tp, Ret>' when 'Ret' is a function type.
   'Ret' is a function type whenever 'Ret Tp::*' is a pointer to member function.
   Attempting to add cv and ref qualifiers to a function type can cause a hard
   compile error.

3. Remove the dummy overload __invoke(Rp Tp::*). It was present to help work
   around . It will be replaced with a different '__invoke' overload that
   represents a bad call to invoke.

After applying this patch the test func.wrap.func.inv/invoke.pass.cpp now
passes.

12ddf2cbd2 Get C++03 __invoke working for bullet 5 of INVOKE.
This patch does a couple of things to get __invoke working for free-functions
and call objects.

1. Turn all uses of declval<Tp>() into declval<Tp&>(). The C++03 __invoke only
   supports lvalues but it will be used when the compiler supports rvalue
   references but not variadic templates. This change makes sure we don't
   generate an rvalue.

2. Call objects for bullet 5 are now passed by reference and not value. Copying
   the functor is incorrect. It will fail to compile for non-copyable functors
   and it will discard cv-qualifiers on the call object, possibly leading to the
   wrong function being called. I suspect that the reason the call object
   was originally taken by value was to support temporary call objects.
   However __invoke is only used internally and it is never given a temporary.

db8c4fd8c7 Merge C++03 and C++11 implementations of mem_fn and __mem_fn.
The implementation of mem_fn doesn't actually require any  C++11 support.
For some reason there were 17 overloads for mem_fn in C++03 when only one
is needed. This patch removes the extra overloads and uses the same implementation
of mem_fn in C++03 and C++11.

__mem_fn does require variadics to implement the call operator. Instead of
having two entirely different implementations of the __mem_fn struct, this patch
uses the same __mem_fn struct but provides different call operators when
variadics are not available.

The only thing left in <__functional_03> is the C++03 implementation of
std::function.

This patch removes a large amount of duplicate code found in both
<__functional_base> and <__functional_base_03>. The only code that remains
in <__functional_base_03> is the C++03 implementation of __invoke and
__invoke_return.

45f63bc07e Cleanup <__functional_03>
<__functional_03> provides the C++03 definitions for std::memfun and
std::function. However the interaction between <functional> and <__functional_03>
is ugly and duplicates code needlessly. This patch cleans up how the two
headers work together.

The major changes are:

- Provide placeholders, is_bind_expression and is_placeholder in <functional>
  for both C++03 and C++11.

- Provide bad_function_call, function fwd decl,
  __maybe_derive_from_unary_function and __maybe_derive_from_binary_function
  in <functional> for both C++03 and C++11.

- Move the <__functional_03> include to the bottom of <functional>. This makes
  it easier to see how <__functional_03> interacts with <functional>

- Remove a commented out implementation of bind in C++03. It's never going
  to get implemented.

- Mark almost all std::bind tests as unsupported in C++03. std::is_placeholder
  works in C++03 and C++11. std::is_bind_expression is provided in C++03 but
  always returns false.

692177d022 Enable and fix warnings during the build.
Although CMake adds warning flags, they are ignored in the libc++ headers
because the headers '#pragma system header' themselves.

This patch disables the system header pragma when building libc++ and fixes
the warnings that arose.

The warnings fixed were:
1. <memory> - anonymous structs are a GNU extension
2. <functional> - anonymous structs are a GNU extension.
3. <__hash_table> - Embedded preprocessor directives have undefined behavior.
4. <string> - Definition is missing noexcept from declaration.
5. <__std_stream> - Unused variable.
