This patch pulls google/benchmark v1.4.1 into the LLVM tree so that any project could use it for benchmark generation. A dummy benchmark is added to `llvm/benchmarks/DummyYAML.cpp` to validate the correctness of the build process. The current version does not utilize LLVM LNT and LLVM CMake infrastructure, but that might be sufficient for most users. Two introduced CMake variables: * `LLVM_INCLUDE_BENCHMARKS` (`ON` by default) generates benchmark targets * `LLVM_BUILD_BENCHMARKS` (`OFF` by default) adds generated benchmark targets to the list of default LLVM targets (i.e. if `ON` benchmarks will be built upon standard build invocation, e.g. `ninja` or `make` with no specific targets) List of modifications: * `BENCHMARK_ENABLE_TESTING` is disabled * `BENCHMARK_ENABLE_EXCEPTIONS` is disabled * `BENCHMARK_ENABLE_INSTALL` is disabled * `BENCHMARK_ENABLE_GTEST_TESTS` is disabled * `BENCHMARK_DOWNLOAD_DEPENDENCIES` is disabled Original discussion can be found here: http://lists.llvm.org/pipermail/llvm-dev/2018-August/125023.html Reviewed by: dberris, lebedev.ri Subscribers: ilya-biryukov, ioeric, EricWF, lebedev.ri, srhines, dschuff, mgorny, krytarowski, fedor.sergeev, mgrang, jfb, llvm-commits Differential Revision: https://reviews.llvm.org/D50894 llvm-svn: 340809
