Move collapseAnonymousBlockChild() to LayoutBlockFlow, and make it non-static.

Move collapseAnonymousBlockChild() to LayoutBlockFlow, and make it non-static.

Some cleanup in collapseLoneAnonymousBlockChild(). Specify a parent rather than
working it out on our own. Both callers have the parent readily available
anyway.

Remove canCollapseAnonymousBlockChild(), since nobody calls it anymore.
