This PR includes a post-order implementation of
dfsFast(an iterative DFS), and is used inpropagateSymbolsUp.Note:
skipChildren()is not included inpostOrderDfsFastsince it doesn't make sense to skip children in a traversal where we visit children before its parents.These changes result in ~2% performance increase in symbol propagation.
