    [Intl] Add benchmark for toLocaleString/localeCompare · e23e1311
    Frank Tang authored
    This is a bit of a performance bottleneck currently and
    we're planning on improving performance by adding caching.
    These benchmarks will allow us to measure the improvements
    Add benchmark tests for
     String.prototype.localeCompare()
     Date.prototype.toLocaleString()
     Date.prototype.toLocaleDateString()
     Date.prototype.toLocaleTimeString()
     Number.prototype.toLocaleString()
    
    Run with
    python -u tools/run_perf.py --binary-override-path \
      out/x64.release/d8 --filter "JSTests/Strings/StringLocaleCompare" \
      test/js-perf-test/JSTests.json
    python -u tools/run_perf.py --binary-override-path \
      out/x64.release/d8 --filter "JSTests/Dates" \
      test/js-perf-test/JSTests.json
    python -u tools/run_perf.py --binary-override-path \
      out/x64.release/d8 --filter "JSTests/Numbers" \
      test/js-perf-test/JSTests.json
