Bazel support is through utils/bazel, and the BUILD files in `benchmark`
just complicate downstream integrates for bazel based builds.

Pulled the latest (b000672), which adds an option to disable -Werror,
which caused issues previously (see for instance
https://reviews.llvm.org/D112012)
Applied https://github.com/google/benchmark/pull/1305 to unblock, as
this issue is causing downstream buildbot failures.
The only change is in llvm/CMakeLists.txt, where we set
BENCHMARK_ENABLE_WERROR to have the same value as LLVM_ENABLE_WERROR.
This patch also introduces a convenience script to pull benchmark from
upstream.

This reapplies a fix from 948ce4e6ed,
whichn't originally submitted upstream. I has now been merged upstream
though, in https://github.com/google/benchmark/pull/1302.
When benchmarks were unified in
5dda2efde5, it lost this change,
but it also lost another local modification, where benchmark's
CMakeLists.txt was modified to comment out adding -Werror.
(This change was part of the original import in
0addd170ab0880941fa4089c2717f3f3a0e4e25a.)
As the benchmark library is built automatically by default, when
building all of LLVM (contrary to the copy in libcxx, which wasn't
built by default), building it with -Werror by default is very brittle.
This fixes building LLVM with MinGW. (It wasn't broken in MSVC
mode, as the benchmark library doesn't add -Werror or anything
equivalent in MSVC mode, and it's unclear if this warning is
enabled in that mode at all.)

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.

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.
