When I was refactoring the unique_ptr.single.ctor tests I added a test
deleter, 'NCDeleter', to deleter.h. Other tests that include deleter.h
redefine the NCDeleter type causing test failures.

One of the last sections of tests that still fail in C++03 are the unique_ptr
tests. This patch begins cleaning up the tests and fixing C++03 failures.
The main changes of this patch:
- The "Deleter" type in "deleter.h" tried to be "move-only" in C++03. However
the move simulation no longer works (see "__rv"). "Deleter" is now copy
constructible in C++03. However copying "Deleter" will "move" the test value
instead of copying it.
- Reduce the unique.ptr.single.ctor tests files from ~25 to 4. There is no
reason the tests were split through so many files.

This patch adds the working parts of r243503. The difference with this patch
is that it doesn't include the HandleLLVMOptions.cmake file.

This change was reverted in r243550 because it broke clang-format builds
(see PR24306).
This patch recommits a fixed version of the original.

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`.

<__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.

Summary: This patch adds special configuration logic to find the compiler_rt libraries required by sanitizers on OS X. The supported sanitizers are Address and Undefined.

Summary: This patch adds proper guards to the is_destructible tests depending on the standard version so that they pass in c++03.

Summary:
In some places in libc++ we need to use the `__atomic_*` builtins. This patch adds a header that provides access to those builtins in a uniform way from within the dylib source.
If the compiler building the dylib does not support these builtins then a warning is issued.
Only relaxed loads are needed within the headers. A singe function to do these relaxed loads has been added to `<memory>`.
This patch applies the new atomic builtins to `__shared_count` and `call_once`.

Automatically enable clang verify whenever the '-verify-ignore-unexpected' flag
is supported.
Failure tests are run using verify if they contain one or more "expected-*"
diagnostics tags. Otherwise they are run normally.
