      [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
