[libcxx-commits] [libcxx] [libc++] Rename bitset benchmark to be self-descriptive (PR #162139)

[Louis Dionne via libcxx-commits]

https://github.com/ldionne created https://github.com/llvm/llvm-project/pull/162139

It's important for the name of each benchmark to fully describe the benchmark since we aggregate the results of all benchmarks in a single .lnt file for analysis.
