[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`.
