This patch puts in the initial framework for incremental reflow. Nodes' styles are no longer recalculated unless the node has changed. I've been hacking on the general problem of incremental reflow for the past couple weeks, and I've yet to get a full implementation that actually passes all the reftests + wikipedia + cnn. Therefore, I'm going to try to land the different parts of it one by one. This patch only does incremental style recalc, without incremental flow construction, inline-size bubbling, reflow, or display lists. Those will be coming in that order as I finish them. At least with this strategy, I can land a working version of incremental reflow, even if not yet complete. r? @pcwalton
