Summary:
This patch adds Sphinx based documentation to libc++. The goal is to make it easier to write documentation for libc++ since writing new documentation in HTML is cumbersome. This patch rewrites the main page for libc++ along with the instructions for using, building and testing libc++.
The built documentation can be found and reviewed here: http://efcs.ca/libcxx-docs
In order to build the sphinx documentation you need to specify the cmake options `-DLLVM_ENABLE_SPHINX=ON -DLIBCXX_INCLUDE_DOCS=ON`. This will add the makefile rule `docs-libcxx-html`.

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`.

Summary:
This patch adds support for LLVM_USE_SANITIZER when being built in-tree and standalone.
This patch does the following things:
1. define the LLVM_USE_SANITIZER option to "" when being built standalone. This also helps show we support it.
2. Translate LLVM_USE_SANITIZER when standalone in a very similar way done in llvm/cmake/HandleLLVMOptions.cmake.
3. Add config.llvm_use_sanitizer to lit.site.cfg.in
4. Add code to translate config.llvm_use_sanitizer's value into the needed compile flags in lit.cfg.
Currently lit.cfg assumes that that the compiler supports '-fno-omit-frame-pointer' while CMakeLists.txt actually checks to see if its supported. We could pass this information to lit but I'm not sure its needed.

Summary:
This patch does two things:
CMake Update:
- Add compiler flag checks for -std=c++11 and -std=c++1y and remove check for -std=c++0x.
- Add configuration option LIBCXX_ENABLE_CXX1Y to prevent/allow -std=c++1y from being chosen as the std version. LIBCXX_ENABLE_CXX1Y is set to OFF by default.
- if LIBCXX_ENABLE_CXX1Y is enabled then set LIBCXX_STD_VERSION to c++1y and fail if the compiler does not support -std=c++1y
- If c++1y is not enabled then use c++11 and fail if the compiler does not support c++11.
Lit Update:
- Update lit.site.cfg.in to capture LIBCXX_STD_VERSION information as config.std.
- Remove mentions of has_cxx0X configuration option.
- Check for `--param std=X' passed to lit on the command line.
- Choose the std for the tests either from command line parameter or (if it doesn't exist) the lit.site.cfg.

This is unnecessary now that the flag handling has been fixed. The flags will
be added properly in the main CMakeLists.txt after the config-ix inclusion which
performs the required check.

libcxx doesn't build with -Werror because of #warnings in its source
code. But when libcxx is built as an external LLVM project, it inherits
LLVM build flags, breaking the build if LLVM_ENABLE_WERROR is enabled.
