    [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
