Summary: This patch adds configuration to CMake and LIT for running the libc++ test-suite to generate code coverage. To use code coverage use following instructions. * Find the clang resource dir using `$CXX -print-search-dirs`. Let <library-dir> be the first library search directory. * `cmake <regular-options> -DLIBCXX_GENERATE_COVERAGE=ON -DLIBCXX_COVERAGE_LIBRARY=<library-dir>/lib/<platform>/libclang_rt.profile.a <source>` * `make cxx` * `make check-libcxx` * `make generate-libcxx-coverage` The reason I want this patch upstreamed is so I can setup a bot that generates code coverage and posts in online for every revision.
