        - assorted speedups to fix perf regression from fixing correctness regression

        * WebCore.exp: exported new methods.
        * WebCore.xcodeproj/project.pbxproj: Added CachedResourceMac.mm
        * bridge/mac/WebCoreFrameBridge.h:
        * bridge/mac/WebCoreFrameBridge.mm:
        * loader/CachedResource.cpp: Removed now obsolete getCFURL.
        * loader/CachedResource.h:
        * loader/mac/CachedResourceMac.mm: Added.
        (WebCore::CachedResource::getNSURLRequest): New method; the NSURLRequest is
        now cached in the CachedObject.
        * loader/mac/FrameLoader.h:
        * loader/mac/FrameLoader.mm:
        (WebCore::FrameLoader::loadedResourceFromMemoryCache): New method - lets
        the WebKit side do faster dispatch for clients that implement the fast path delegate.
        * loader/mac/LoaderFunctionsMac.mm:
        (WebCore::CheckCacheObjectStatus): Instead of calling several FrameLoader methods,
        just call loadedResourceFromMemoryCache.
        * loader/mac/WebFrameLoaderClient.h:

        - various performance improvements for resource delegate dispatch.

        - avoid any ObjC messaging when fetching the WebView
        - avoid ObjC calls to WebView to get resource load delegate and impl cache
        - cache actual method pointers, not just the fact that the method is present
        - added a new SPI resource load delegate method which allows clients to get
          just one message in case of synchronously loading from memory cache; if this
          is implemented you don't get the normal delegate calls in that case.
        - various other minor tweaks
