If a script calls Math.pow a lot, and the second argument is either int32 or double, the JITs always pass it as double. This means Math.pow should also use powi if the second argument is an integer-valued double.
This may be a very small v8-raytrace/kraken-darkroom win, but I had to write the patch anyway to measure that so let's just fix it.
