bzbarsky%mit.edu ba5badedcb Change the FrameNeedsReflow API to pass the dirty flags to be added directly to 
the method, instead of setting them before calling the method.  That way we can
avoid reflowing the ancestor of a reflow root which is not itself dirty but has
dirty children.  This also makes it harder to set dirty bits inconsistently
with the FrameNeedsReflow call.  Bug 378784, r+sr=dbaron, pending rbs' review
on the mathml parts.
