           Summary: [v8] do not copy data twice when converting short v8
                    string into WebCore::String
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: antonm at chromium.org

Using WebCore::String::String(const UChar*, int length) leads to another copy
of data, so we'd better use String::createUninitialized directly
