Add SpiderMonkey JSON/Regex benchmark

- Add spidermonkey-json benchmark using JSON.parse/stringify
- Add SpiderMonkey Regex benchmark
- Scaled all spidermonkey benchmarks to take aroun ~100M cycles
  per iteration on my test machine which is hopefully a balanced
  size.
- Rename base spidermonkey benchmark to markdwon
