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.
