           Summary: Type tags in NodeFlags could be compressed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: morrita at google.com

We have type tags like:

        IsTextFlag = 1,
        IsCommentFlag = 1 << 1,
        IsContainerFlag = 1 << 2,
        IsElementFlag = 1 << 3,
        IsStyledElementFlag = 1 << 4,
        IsHTMLFlag = 1 << 5,
        IsSVGFlag = 1 << 6,
        InDocumentFlag = 1 << 9,
        IsShadowRootOrSVGShadowRootFlag = 1 << 16,

And these are apparently redundant. We could compress these.
