Shopify/yjit-bench

Small set of benchmarks and scripts for the YJIT Ruby JIT compiler project, which lives in the Shopify/yjit repository. The benchmarks are found in the benchmarks directory. Individual Ruby files in benchmarks are microbenchmarks. Subdirectories under benchmarks are larger macrobenchmarks. Each benchmark relies on a harness found in ./harness/harness.rb. The harness controls the number of times a benchmark is run, and writes timing values into an output file.
