Instead of computing whether a block's children are inline based on the first child, make it an imperatively-set flag. This gives us some flexibility to ignore things like text nodes inside a <table>, for example. I'm still unsure what the "correct" way to deal with those will be. We'll find out sooner or later. :^)
