        Make RegExp GC allocated
        https://bugs.webkit.org/show_bug.cgi?id=61490

        Make RegExp GC allocated.  Basically mechanical change to replace
        most use of [Pass]RefPtr<RegExp> with RegExp* or WriteBarrier<RegExp>
        where actual ownership happens.

        Made the RegExpCache use Strong<> references currently to avoid any
        changes in behaviour.

        CachedResource overhead size calculation ignores the actual size of the URL
        https://bugs.webkit.org/show_bug.cgi?id=61481

        CachedResource::overheadSize is used to determine the size of an entry in the memory cache to know when to evict
        it.  When the resource is a large data: URL, for example representing image or audio data, the URL size itself
        can be significant.

        This patch uses an estimate of actual number of bytes used by the URL that is valid for ASCII urls and close for
        other types of strings instead of a fixed number.

        * loader/cache/CachedResource.cpp:
        (WebCore::CachedResource::overheadSize):
