[libc++] Explicitly mention vector_bool in the name of benchmarks

We have some benchmarks that were benchmarking very specific functionality,
namely the optimizations in vector<bool>::iterator. Call this out in the
benchmarks by renaming them appropriately. In the future we will also
increase the coverage of these benchmarks to test other containers.
