      [js-perf-test] Add Array#{indexOf,includes} micro-benchmark · 591c92ac
      Mathias Bynens authored
      This patch adds a micro-benchmark comparing Array#indexOf,
      Array#includes, and a roughly equivalent `for` loop.
      
      The benchmark can be used to measure any Array#{indexOf,includes}
      optimizations we implement in the future.
      
      Test:
      
          tools/run_perf.py --binary-override-path=out/x64.release/d8 \
            --filter=JSTests/ArrayIndexOfIncludesPolymorphic \
            --extra-flags=--trace-turbo test/js-perf-test/JSTests.json
