This patch is one of the series of optimizing the case, string.match(/regexp/) thing. When evaluating /regexp/, new RegExpObject is created every time. However, basically, we do not have much interest on this object. At the end of the patch series, we should make this PhantomNewRegexp in OAS phase. As a first step of these NewRegexp optimization, we would like to inline it by using allocateJSObject.
