Mircea Trofin b2fbd45d23 Revert "Reland "[benchmarks] Move libcxx's fork of google/benchmark and llvm/utils'"""
This reverts commit 1ee32055ea.

We hit additional bot failures; in particular, Fuchsia's seems to be
related to how CMakeLists are ingested, see https://ci.chromium.org/ui/p/fuchsia/builders/toolchain.ci/clang-linux-x64/b8830380874445931681/overview

Mircea Trofin 1ee32055ea Reland "[benchmarks] Move libcxx's fork of google/benchmark and llvm/utils'""
This reverts commit e7568b68da and relands
c6f7b720ec.

The culprit was: missed that libc also had a dependency on one of the
copies of `google-benchmark`

Also opportunistically fixed indentation from prev. change.

Some buildbots are failing, will investigate and reland.

Mircea Trofin c6f7b720ec [benchmarks] Move libcxx's fork of google/benchmark and llvm/utils'
under third-party

This change:
- moves the libcxx copy of `google/benchmark` to
`third-party/benchmkark`
- points the 2 uses of the library (libcxx and llvm/utils) to this copy

We picked the licxx copy because it is the most up to date.

Eric Fiselier b08d8b189c [libcxx] Add support for benchmark tests using Google Benchmark.
Summary:
This patch does the following:

1. Checks in a copy of the Google Benchmark library into the libc++ repo under `utils/google-benchmark`.
2. Teaches libc++ how to build Google Benchmark against both (A) in-tree libc++ and (B) the platforms native STL.
3. Allows performance benchmarks to be built as part of the libc++ build.

Building the benchmarks (and Google Benchmark) is off by default. It must be enabled using the CMake option `-DLIBCXX_INCLUDE_BENCHMARKS=ON`. When this option is enabled the tests under `libcxx/benchmarks`  can be built using the `libcxx-benchmarks` target.

On Linux platforms where libstdc++ is the default STL the CMake option `-DLIBCXX_BUILD_BENCHMARKS_NATIVE_STDLIB=ON` can be used to build each benchmark test against libstdc++ as well. This is useful for comparing performance between standard libraries.

Support for benchmarks is currently very minimal. They must be manually run by the user and there is no mechanism for detecting performance regressions.

Known Issues:

* `-DLIBCXX_INCLUDE_BENCHMARKS=ON` is only supported for Clang, and not GCC, since the `-stdlib=libc++` option is needed to build Google Benchmark.
