* we know all types frames may be cast to at compile time, so instead of extensible GUID IIDs, use a big enum (see nsQueryFrame::FrameIID)
* eliminate all vestiges of refcounting, since frames aren't refcounted
Some frames (SVG frames in particular) still implement nsISupports-derived interfaces, for example nsISVGValue. There is a FrameIID for nsISVGValue that lets you go from a frame to the XPCOM interface, but you can't query back.

nsITextControlFrame didn't have an IID the first time around, but this wasn't a compile error because nsITextControlFrame::kFrameIID inherited from nsIFormControlFrame::kFrameIID. I've added a static analysis pass to verify the correct behavior, since I can't figure out a way to make the compiler do it.

This patch locally causes two REFTEST-UNEXPECTED-PASS for Bidi stuff. It's possible that I accidentally fixed a bug, but I'm not sure, so I'm going to wait for the tinderboxes to confirm my local results.
CellData keeps track of row versus col spans.
nsColFrame keeps track of what cell contributed to constrained width.
nsCellMap::GetCellFrameAt replace with GetCellInfoAt
simplified nsTableCellFrame::RecalcLayoutData and removed FindLargestMargin, CalculateMargins, CalculateMargins
simplified nsTableFrame::RecalcLayoutData and removed AppendLayoutData
Added gsDebugReflow capability, remove all existing debug printf
