[libc++] Make benchmarks forward-compatible with the test suite (#114502)
This patch fixes warnings and errors that come up when running the
benchmarks as part of the test suite. It also adds the necessary Lit
annotations to make it pass in various configurations and increases the
portability of the benchmarks.
