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
